3.2. Checking Wiring
Wiring between devices (or switches) of CC-Link IE TSN should be compliant with ANSI/TIA/EIA568 Category 5e. When installing, confirm the following items.
1) Wiring length (see Section 3.2.1)
2) Number of connectors (see Section 3.2.2)
3) Connection between connectors (plug/jack) and cable (See Section 3.2.3.)
4) Transmission characteristics (see Section 3.2.4.)
3.2.1. Wiring length
In the CC-Link IE TSN specification, the maximum physical wiring length between devices is 100
m. (Devices means the CC-Link IE TSN devices or switches. Passive components such as
connectors connecting cables are not included in the device and are considered part of the wiring.)
In the ANSI/TIA/EIA-568-B standard which specifies the wiring specifications, the wiring between
devices is called a channel. Assuming a state of combining cables and connectors, thetransmission characteristics of the channel are specified apart from the transmission characteristicsof the connector alone.
In the example in Figure 3.2-1, there are five channels in total connecting the devices, the wiring
length of each channel is 100 m or less, and each channel is required to satisfy the transmission
characteristics specification.

Wiring between devices, that is, the transmission characteristics of each channel must satisfy
the channel specification value. Depending on the type of cable and the ambient temperature, it
may not be possible to extend the wiring up to 100 m. In particular, the total amount of insertion
loss and propagation delay of the wiring ports (cables, connectors) used needs to be thespecification value of the channel or less. For details, refer to 3.2.4.Transmission characteristics.

CLPA

BAP-C3007ENG-001-E(16/42)

In particular, use care with regard to the following cases.
• For twisted-wire conductor cables
Generally, twisted-wire conductor cable has a large insertion loss and may not satisfy
the insertion loss specification of the channel when the wire is extended 100 m.
* In Category 5e of ANSI/TIA/EIA-568-B, the specification value of the channel is
specified by assuming the state of a combination of a 90 m single-wire conductor
cable and 10 m twisted-wire conductor cable. Since the insertion loss of the twistedwire conductor cable is larger than that of the single-wire conductor cable, thetransmittable distance becomes shorter. For details, check with the cablemanufacturer.
When wiring a long distance, use a single-wire conductor cable.
• When the conductor size is thin
Generally, when the conductor is thinner than 24 AWG (0.5 mm), the insertion loss islarge and the transmittable distance becomes short.
• For special cables, such as for moving sections
Before use, check the transmission characteristics (especially insertion loss andpropagation delay) and the transmittable distance indicated by the cable manufacturer.
• When multiple cables are connected
For example, if a device is installed inside the panel and short cables are used in thepanel, the cable length, insertion loss, and propagation delay inside the panel also need
to be taken into account. In addition, when connecting multiple cables using a relay
connector (jack - jack) or the like, it is necessary to take into consideration insertion loss
and propagation delay of all cables and connectors between the devices.
• When the ambient temperature is high
The maximum length between devices varies depending on the temperatureenvironment (cable installation environment). Decide the cable length between devices
based on Table 3.2-1. For details, calculate the insertion loss between devices
according to "3.2.4. Transmission characteristics" and confirm that it is within thespecified value.
The higher the temperature, the larger the insertion loss of the cable and the shorterthe transmittable distance becomes. As an example of typical shielded cables, insertion
loss increases by about 0.2% per 1°C. The specified insertion loss value of the cable isusually based on at 20°C. When the cable becomes hot even partially, it is necessary
to satisfy the specified insertion loss in the state where the temperature has risen.
Also, if there is no margin to the channel specification value at 20°C, there is a risk of
exceeding the specified insertion loss value due to changes in the ambient temperature.
Calculate the insertion loss of cable at high temperature based on the temperature
coefficient specification of the cable manufacturer.

3.2.2. Number of connectors
The number of connectors in one channel shall be four or less. However, confirm the following
conditions.
• Plugs connected to the device at both ends of the channel are not counted. One plug andjack pair where cables are relayed is counted as one and make sure that the number ofconnectors is four or less.
If a relay connector (jack-jack) is used, calculate by assuming that the number of connectors is two
with one relay connector.
3.2.3. Precautions on connectors and cable connections
If wiring processing is insufficient, communication failure occurs easily due to deterioration of thewaterproof performance of M12 connectors, poor contact between the cable and connector, andother reasons. Therefore, follow the processing procedure specified by the connector manufacturer
and work with due care.
3.2.3.1. RJ45 connector
When connecting cables and connectors (plug/jack), follow the wiring method specified in the
ANSI/TIA/EIA-568 standard and the wiring method/work procedure specified by the connector
manufacturer.
In the ANSI/TIA/EIA-568 standard, the following T568A and T568B wiring patterns are specified.
Other wiring methods can cause miswiring and there is a high risk of communication failure
because the prescribed transmission characteristics cannot be obtained.

3.2.3.4. Precautions on connector connection
If wiring processing is insufficient, communication failure occurs easily due to deterioration of thewaterproof performance of M12 connectors, poor contact between the cable and connector, andother reasons. Therefore, follow the processing procedure specified by the connector
manufacturer and work with adequate caution.
Make sure that the proper cable and connector combination are used in terms of the wire
conductor size (AWG), conductor structure (single-wire, twisted-wire), external diameter of theinsulator, external diameter of cable, shielding, category, and others.
● Cable conductor structure
Cables are classified into single-wire and twisted wire, and also connector types include singlewire, twisted wire, and the type for both wires. Therefore, check that the connection isappropriate.
Certain combinations cannot be used. For example, a single-wire cable cannot be combinedwith a connector for twisted wire.
Refer to Appendix "A1. Conductor Structure of Cable for FA".
● External diameter of cable
Check that the combination of cable external diameter and connector is appropriate.
If the external diameter range is not appropriate, there is a risk of breakage of the connector
or a decrease in the cable retention strength.
● Shield and shielded line processing
In accordance with the treatment procedure of the connector manufacturer, connect the shieldof the connector and the shield wire of the cable tightly.
● Pin terminal height (Crimp Height)
For RJ45 connectors of the type that push the pin terminal, it is important that the pin terminal
height (crimp height) is uniform and within the specified value. Crimp height outside thespecified value could cause communication failure.
Refer to Appendix "A2. Pin Terminal Height (Crimp Height)".
● Dedicated tool
Always use the special tools specified by the connector manufacturer, if any.
Failure to do so could cause incorrect wire connection.
Also, in some cases normal wiring cannot be performed due to deterioration or breakage of
special tools. Therefore, perform periodic inspection of special tools.
● Reprocessing of connectors
Re-treatment of connector is not recommended.
If a connector is re-treated, communication errors may occur due to deformation or breakageof the connector.

CLPA

BAP-C3007ENG-001-E(22/42)

3.2.4. Transmission characteristics
The wiring between devices must meet the transmission characteristic standard of the channel ofthe ANSI/TIA/EIA-568-B Category 5e standard. Even if wiring is performed using wiring materials(cables and connectors) that meet the Category 5e standard, if the construction method is
inappropriate, the transmission characteristic standard of the channel may not be satisfied. When
wiring is completed, it is recommended to use a field tester to measure and check whether the
specification values are satisfied.
The main transmission characteristics specified in the Category 5e standard include the following
items. Refer to the ANSI/TIA/EIA-568-B Category 5e standard for details of the specification values.
• Insertion loss (IL)• Near end crosstalk (NEXT)• Power sum near end crosstalk (PSNEXT)• Equal level far end crosstalk (ELFEXT)• Power sum equal level far end crosstalk (PSELFEXT)• Return loss (RL)
• Propagation delay• Delay skew
Of the above, insertion loss and propagation delay can be roughly calculated from the specification
values of the cable and the connectors used for wiring. In particular, when using the cable at alength close to the standard upper limit of 100 m, if using a special cable such as a cable formovable parts or a cable with a small conductor size, or if using a cable under an environment
where the ambient temperature is particularly high, it is necessary to confirm beforehand whether
the specification values of the channel are satisfied with the configuration to be wired and theambient temperature.
If on calculation it does not satisfy the specification values of the channel, to meet the channel
specification values review the layout and shorten the total length of the wiring, shorten as short as
possible the length of wiring that uses a cable with a small conductor size or a cable for a movablepart, or use cables with a smaller insertion loss or propagation delay, and others. If this is notpossible, consider inserting a switch or the like in the middle.
Also, for items other than insertion loss and propagation delay, it is impossible to calculate easily
from the cable/connector specification value, and it is necessary to measure using items such as afield tester.

● Rough estimation of delay time
When two types of cables are used and connected using multiple connectors (plug + jack)Propagation delay at 10 MHz per 100 m of cable 1: Delaycable1 (ns/100 m)(Usually, 545ns/100 m or less.)
Propagation delay at 10 MHz per 100 m of cable 2: Delaycable2 (ns/100 m)
Total length of cable 1 and cable 2: Lcable1, Lcable2 (m)Propagation delay of the connector (plug + jack): Delayconn (ns) (Usually, 2.5 ns or less.
Calculate using 2.5 ns.)
Number of connectors: n
Propagation delay of channel (wiring between devices): Delaychannel (ns)
Delaychannel = Delaycable1 × Lcable1 /100 + Delaycable2 × Lcable2/100 + Delayconn × n ·· (Formula A)
Confirm that the channel propagation delay obtained above is not more than the channel
specification value (555 ns).
The following shows an example calculation when using a combination of a single-wireconductor cable (cable 1) and a special cable with a large propagation delay (cable 2).
Propagation delay at 10 MHz per 100 m of cable 1: Delaycable1 = 545 (ns/100 m)
Propagation delay at 10 MHz per 100 m of cable 2: Delaycable2 = 600 (ns/100 m)
Propagation delay of connectors (plug + jack): Delayconn = 2.5(ns)Number of connectors: n = 4
Propagation delay of channel (wiring between devices): Delaychannel (ns)
Delaychannel = 545 × Lcable1/100 + 600 × Lcable2/100 + 2.5 × 4
Example 1: When the total length of cable 1 and cable 2 is 80 m and 3 m, respectively,
Delaychannel = 545 × 80/100 + 600 × 3/100 + 10 = 464 (ns)Since the propagation delay specification value 555 ns of the channel is satisfied, thislayout can be used.
Example 2: When the total length of cable 1 and cable 2 is 40 m and 60 m, respectively,
Delaychannel = 545 × 40/100 + 600 × 60/100 + 10 = 588 (ns)Since the propagation delay specification value 555 ns of the channel is not satisfied, thislayout cannot be used.
The propagation delay of the channel is designed to be 555 ns, which is the specification valueof the channel, when a total of 100 m of cable that satisfies the propagation delay (545 ns/100m) prescribed in the ANSI/TIA/EIA-568-B Category 5e standard is used and connectors(propagation delay 2.5 ns) are used in four locations. Therefore, calculation of the propagation
delay is unnecessary when a special cable with a large propagation delay is not used.

● Rough estimation of insertion loss
When two types of cables are used and connected using multiple connectors (plug + jack)Insertion loss per 100 m of cable 1: ILcable1 (dB/100 m)
Insertion loss per 100 m of cable 2: ILcable2 (dB/100 m)
Total length of cable 1 and cable 2: Lcable1, Lcable2 (m)Insertion loss of connector (plug + jack): ILconn (dB)
Number of connectors: nInsertion loss of channel (wiring between devices): ILchannel (dB)ILchannel = ILcable1 × Lcable1/100 + ILcable2 × L cable2/100 + ILconn × n ···(Formula B)
Temperature conversion formula of cable insertion loss
Insertion loss per 100 m of cable 1 at 20°C: ILcable1, 20°C (dB/100 m)
Temperature coefficient of insertion loss of cable 1: kcable1 (%)
Cable temperature: t (°C)
Insertion loss per 100 m of cable 1 at t (°C): ILcable1, t°C (dB/100 m)
ILcable1, t°C = ILcable1, 20°C × (1+ (t-20) × k/100) ··· (Formula C)
Therefore, when calculating the insertion loss of the channel at t°C, instead of using Formula B,
ILcable1, ILcable2, use ILcable1, t°C, ILcable2, t°C of Formula C.
Confirm that the channel propagation delay obtained above is the channel specification value
or less. Originally it is necessary to meet the channel specification value in the whole band of 1
MHz to 100 MHz. However, as a rough judgment method, it can usually be judged by insertion
loss at 100 MHz.
The following shows a calculation example where a combination of a single-wire conductor
cable (cable 1) and a twisted-wire conductor cable (cable 2) is used and the ambient
temperature rises up to 60°C.
Insertion loss per 100 m of cable 1 at 20°C: ILcable1, 20°C = 22.0 (dB/100 m)
Temperature coefficient of insertion loss of cable 1: k cable1 = 0.2 (%)
Insertion loss per 100 m of cable 2 at 20°C: ILcable2, 20°C = 26.4 (dB/100 m)
Temperature coefficient of insertion loss of cable 2: k cable2 = 0.2(%)
Cable temperature: t = 60 (°C)
Insertion loss of connector (plug + jack) at 100 MHz: ILconn = 0.4 (dB)
Number of connectors: n = 4
Insertion loss of channel (wiring between devices) at 100 MHz: ILchannel (dB)ILchannel = (22.0 × (1+ (60-20) × 0.2/100)) × Lcable1/100 + (26.4 × (1 + (60-20) × 0.2/100)) ×
Lcable2/100 + 0.4 × 4= 23.76 × Lcable1/100 + 28.51 × Lcable2/100 + 1.6
Example 1: When the total length of cable 1 and cable 2 is 80 m and 3 m, respectively,
ILchannel = 23.76 × 80/100 + 28.51 × 3/100 + 1.6 = 21.46 (dB)
Since the insertion loss specification value 24 dB of the channel at 100 MHz is satisfied, thislayout can be used.
Example 2: When the total length of cable 1 and cable 2 is 50 m and 40 m, respectively,
ILchannel = 23.76 × 50/100 + 28.51 × 40/100 + 1.6 = 24.88 (dB)
Since the insertion loss specification value 24 dB of the channel at 100 MHz is not satisfied,
this layout cannot be used.
Note that the above is only a rough judgment method and for various reasons it does notnecessarily agree with the actual measured value of channel insertion loss. For the insertion loss
specification, set the cable length with a margin. Also, after wiring, it is recommended to use ameasuring instrument such as a field tester to measure under the actual measuring conditions toconfirm that there is a margin.

3.3. Installation and Wiring
3.3.1. Precautions on installation● Installation route• Use ducts or cable racks as much as possible in the installation route.
• In the case of a pipeline such as a conduit, select the pipe diameter considering thedimensions of connectors, boots, and others. Also, when providing a pull box in the middle
of a pipeline, select one that satisfies the allowable bending radius of the cable.
• Use a dedicated installation route as much as possible.
• The route should be free of water and oil intrusion, and high/low temperatures outside theapplicable ambient temperature.
• When constructing an installation route with a special environment inside a factory, selectenvironmentally friendly materials.
Example: Heat resistance, oil resistance, movable parts, and others• For environmental resistance of each material, refer to the specifications of eachmanufacturer.
● Cable minimum bending radius• Confirm the specifications of each cable manufacturer and use the cable by adhering to theminimum bending radius.
• The minimum bending radius is the radius that can guarantee the characteristics over along period of time after fixing the cable.
• If you are forced to use a cable below the minimum bending radius, there is a risk that thetransmission performance may deteriorate or the cable may be broken.
● Allowable tension• To the extent possible, do not apply tension to the cable.
• There is a risk that the connector may come out, breaking the cable or causing inability tosatisfy the transmission performance.
• At installation: When it is unavoidable that tension will be applied, use within the allowabletension of the cable.
(Confirm with the cable manufacturer.)• When fixing: Pay attention to the wiring length/fixing method so as not to apply tension to
the cable.
● Notes on noise countermeasures• In order to prevent induced noise, lay the power line and signal line as far apart as possible.
• Do not lay the cable in a panel where high pressure devices are installed.
• Attach a surge suppressor to a high noise device.
● Cable side pressure• Do not apply side pressure through too much packing or pinching of cables to/with cable
protective materials such as wire protectors or pipe, or excessive tightening of the cableties.
• It may become unable to satisfy the transmission performance.
● Handling of connectors• Before connecting, be careful not to apply external force such as side pressure or impact
the connector.
• In particular, both the metal part and plastic resin part of the terminal part of the RJ45 plugare easily deformed, so careful handling is required.
• If connecting with a deformed connector, it could cause a malfunction or damage to theconnection part on the device side due to a poor connection.
• If there is a possibility that an external force has been applied to the connector, check for
deformation before use.
Refer to Appendix "A3. Deformation of Connectors".

CLPA

BAP-C3007ENG-001-E(26/42)

● Stress on the connector connecting part
• Make sure not to apply stress on the connector connecting part.
• If stress is applied on the connector connecting part due to the weight of the cable, neckbending, twisting, shaking, transportation, or inadvertent pulling, it could cause breaking of
the unit or connector, malfunctions due to poor connection, or communication failure that
occurs over time.
• Since the conductor of the single-wire conductor cable is hard, do not apply stress to theconnector connecting part.
Furthermore, when wiring a short distance, it becomes easy for stress to be applied to theconnector connecting part.
• When wiring a short distance, it is recommended to use a twisted-wire conductor cable or
movable cable that is flexible and easy to handle.
● Waterproof performance of M12 connector• Refer to the manual of the unit and others.
● Wiring to movable parts• When wiring to a movable part, use a cable dedicated to the movable part.
Also, in order to prevent early disconnection, pay attention to the following when wiring.
• Check with the manufacturer about bending characteristics such as the minimum bending
radius of the cable.
• Do not bend, kink or twist the cable.
• Do not damage the cable sheath.
• Minimize cable fixing locations.
• Do not forcefully fix the cable at a location where the cable moves.
• Wire with the optimum length.
● Others• When performing connection of cables, make sure that the power supply andcommunication power supply of connected devices are all OFF.

3.3.2.1. Additional explanation about grounding(1) Grounding types

When classifying grounding of CC-Link IE TSN compatible products (devices) by purpose, thetypes of grounding are roughly divided into two categories (Figure 3.3-2):
1. Protective grounding intended to protect people from electric shock and leakage
2. Functional grounding for securing communication reliability

The grounding of the shielded wire of the cable for CC-Link IE TSN is for functional grounding
to secure the reliability of communication.

Figure 3.3-2 Display of grounding terminals(2) Additional information about the grounding method

Protective grounding and functional grounding shall be dedicated grounding (Figure 3.3-3), or
common grounding (Figure 3.3-4) where grounding wires are laid down individually up to thegrounding point. For common grounding (Figure 3.3-5), noise can enter from the protective
grounding to functional grounding and communication with CC-Link IE TSN can be unstable.
In particular, if the protective grounding and the functional grounding (the shielded wire of thecable for CC-Link IE TSN) of driving devices such as inverters and servos are commonly
grounded, the possibility of unstable communication increases.
1) Use copper wire of 1.6 mm or more diameter, or 2 mm2 or more for the grounding wire offunctional grounding.
(For the grounding wire to the grounding point, it is recommended to use a thick copper wire (14mm2 or more is recommended) and lay it as short as possible.)

4.1.3. Installation and wiring
4.1.3.1. Precautions on installing cable
4.1.3.1.1. Installation
When installing optical cables, make sure to observe the following precautions.
● Installation route• Use pits, ducts or cable racks as much as possible in the installation route.
• In the case of a pipeline such as a conduit, select the pipe diameter while taking thedimensions of the connector and others into consideration. Also, when providing a pullbox in the middle of a pipeline, select one that satisfies the allowable bending radius of
the cable.
• Use a dedicated installation route as much as possible. When sharing with other cables,
lay the optical fiber cable last.
• The route should be free of water and oil intrusion, and high/low temperatures outside theapplicable ambient temperature.
● Pipeline• Do not directly draw the cable; instead fix it to a cable-extending rope and lay it.
Depending on the structure, some cables can be drawn directly so check with the
manufacturer.
• Confirm the specifications of each cable manufacturer and use the cable by adhering to
the minimum bending radius.
• The minimum bending radius is the radius that can guarantee the characteristics over along period of time after fixing the cable.
• If you are forced to use a cable below the minimum bending radius, there is a risk that thetransmission performance may deteriorate or the cable may be broken.
● Precautions on extending lines• The pulling speed of the cable shall be 10 m/min or less and perform tip drawing. Also,
extend the line under 1/2 or less allowable tension so that the tension applied to thecable is even.
• The bending radius at the time of line extension should be at least twice the allowablebending radius.

CLPA

BAP-C3007ENG-001-E(35/42)

• While installing, make sure not to twist the cable. In particular, since some hanger rollers
have a structure that tends to cause twisting, it is recommended to use a metal wheel
when installing a long cable.
• Be careful not to cause kinking (local bending) of the cable.
● Protection of allowable tension• When installing a cable vertically or in the case of aerial wiring, support so that thetension due to the weight of the cable itself does not exceed the allowable tension.
● Prevention of moisture infiltration• Generally, the optical fiber itself has poor water resistance and water infiltration from theend of the optical cable may have an adverse effect in the long term. Furthermore, insome cases, dew condensation caused by the temperature gradient of the optical cableinstallation route infiltrates inside the optical cable, which could adversely affect thecable. When installing an optical cable, make sure to provide waterproofing on the end of
the optical cable.
• POF cable is designed to be used indoors. Do not use it outdoors. In an environment
where moisture infiltrates from the end of the POF cable, provide waterproofing on the
POF cable end.
● Protection of the connector part• When installing a cable, do not bend the connector part and protect the part using a vinyl
hose or a pulling eye. Also, the connector part is very weak to shock and tension, so do
not pull it.
• Before connecting, be careful not to apply external force such as side pressure or impact
the connector.
• Do not remove the protective cap of the optical connector until the connector is connected.
• Do not touch the tip of the optical connector or bump it.
● Wiring to movable parts
When wiring to a movable part, use a cable dedicated to the movable part.
Also, in order to prevent early disconnection, pay attention to the following when wiring.
• Check with the manufacturer about bending characteristics such as the minimum bending
radius of the cable.
• Do not bend, kink or twist the cable.
• Do not damage the cable sheath.
• Minimize cable fixing locations.
• Do not forcibly fix the cable at a location where the cable moves.
• Wire with the optimum length.
● Others• For waterproofing purposes, seal both ends of the cable except during work.
• Use care while handling because the tip of the optical fiber is sharp.
• Do not touch the tip of the optical connector or bump it.
• Since vinyl tape and binding bands containing migratory plasticizer may affect the opticalcharacteristics of optical fiber, check beforehand for any such influence in theenvironment.
• When side pressure or twist is applied to the optical fiber, the optical cable itself deforms,
stress is applied to the internal optical fiber, transmission loss increases, as a result, thecable could break. Do not tighten the optical cable strongly using a nylon band (tie wrap)
or the like as the same condition occurs when bundled.
• When fixing the cable with a cable tie or the like, do not apply tension with the cable bent
at the cable tie fixing part.
• CLETOP-S (Type-B) made by NTT-AT is recommended for cleaning of the fiber tip.

4.1.3.1.2. Fusion splicing and adapter connection
When performing fusion splicing, it is recommended to make a request to a specialized cablemanufacturer.
When performing each connection, pay attention to the following items.
● Precautions on fusion splicing• Follow the procedure described in the instruction manual of the fusing machine (othertools) to be used. In addition, always observe precautions written in the manual.
• Never fuse the core wire in a twisted state.
● Protection of connected locations• Set the fusion splicing and adapter connection locations using a termination box so thattension is not applied to the connection locations. Also, secure a space to install atermination box. The size increases as the number of connections increases. However, it
is available from around 15 cm × 10 cm. Since a different termination box is used
depending on the number of connections, the connection type, and the shape of thecable to be connected, contact the distributor of the optical fiber cable for details.
● Connection loss
• Fusion splicing and adapter connections cause loss at the connection location. Read thecontents of "4.1.2.4 Transmission characteristics" and make sure that the line loss iswithin the judgment value.

A. Supplementary Explanation Supporting Twisted Pair Cables
A1. Conductor structure of FA cable
Different kinds of conductors are used depending on the application.
In line with that, RJ45 connectors (plugs) include single-wire, twisted-wire, and common types.
Certain combinations cannot be used. For example, a single-wire cable cannot be combined witha connector for twisted wire.

Table A-1 Cable types
Application
For fixed wire
For fixed wiring, good flexibility but shortcommunication distanceFor movable parts and othes (depends on the
manufacturer's specifications)

For the conductor thickness, the US wire gauge standard (AWG: American wire gauge) is used.
The larger the number, the smaller the diameter. In Japan, the unit called sq of the JIS standard
may be used.
It is important to match the thickness and type of conductors and the overall dimensions of thecable to the compatible cable specifications of the connector.

The height of the part where the RJ45 plug terminal fixes the wire core. Measuring the pin terminal
height is one of the important management items to check connection reliability.
Pin terminal height lower limit: 5.89 mm, Upper limit: 6.15 mm

Pin terminal
heightFigure A-1-2 Pin terminal height of RJ45 connector (plug)
If the pin terminal height is smaller than the specified value, it indicates that the plug is tightenedexcessively. In such a case, after it is inserted in the jack, contact with the pins of the jack weakens.
If the pin terminal height is larger than the specified value, it indicates that the fixing of the plugterminal and the core wire is weak. In such a case, there is a possibility of a conduction failure, anincrease in the contact resistance value, or the wire conductor could easily come off. Also, after
inserting the connector into the jack, the jack pin may be deformed.
Always use the special tool specified by the manufacturer so as to achieve a uniform height.

Figure A-1-3 Example of uneven pin terminal height of crimp type RJ45 connector (plug)
A3. Deformation of connector
Before connecting units, be careful not to apply external force such as side pressure or impact theconnector.
Connecting with a deformed connector could cause a malfunction or damage to the connection
part on the device side due to poor connection.
To prevent external damage of the connector before connecting, it is effective to protect theconnector using a tube, cushioning material or the like.
