Protection function

X:Center offset(mm)Y:Operating distance(mm)Operating area

186420246X
8Reverse connection protection ... This function protects the circuit by preventing current from flowing to the internal circuit when +24V and 0V are connected
in reverse on the power supply line of the base.
Overheat protection ... This function is that measures the temperature inside the output section and stops the power supply when
the temperature exceeds a certain level. When the temperature drops, it restarts.
Short-circuit protection ... This function turns off the output for a certain period of time to protect the circuit when a current
exceeding the specification flows through the signal output line due to wiring without load.
Overcurrent Protection ... This function detects the current inside the output section and stops transmitting for a certain periodof time when the current exceeds a certain value, thereby protecting the circuit.
TA18C02_03
Output surge absorption protection...A surge absorption circuit is built in to protect the output circuit.
Metal facing protection of the head ... This function protects the circuit by stopping transmission for a certain period of time
when metal is detected.

Installation method
・To avoid the influence of surrounding metals and mutual interference between products, be sure to open a space larger
than the value shown in the table below. In addition to the mounting surface, only one surface of A (periphery) can bein contact with metal. (Fig. 1) The screw tightening torque is 1.5N･m.

Type code

A(Surroundings) B(depth)

・Use a constant voltage power supply such as a switching power supply.
(If a power supply with ripples above the rating, such as a full-wave rectified power supply, is used, it may cause malfunction.)

・If the power supply exceeds the rated voltage, there is a risk of overheating and ignition.
Before supplying power, be sure to check that the power supply is specified in the specifications.

(Fig. 1) Arranged with a space

・When wiring the cable by bending it, use the cable outlet.
Install so that the cable is straight (approximate: about 10 mm)
Install the cable with a bending radius of 50 mm or more. (Figure 2)

・Design it so that it can be used under the wiring and surrounding environment conditions specified in the specifications.
Also, design to satisfy the "transmission distance", "center offset", "output voltage", and "output current". Designs outside thespecifications may cause unexpected malfunctions, troubles, and malfunctions due to deterioration of internal parts.

50mm

・Excessive force on the cable during installation to avoid excessive
stress Please do not pull with.

・The remote coupler system is a system for supplying and transmitting power and signals without contact. Do not use it forany purpose other than this one.

・When wiring for installation, maintenance, failure, etc., be sure to check that the main breaker (power panel) is cut before
performing the work. If you work while the line is live, you may get an electric shock or malfunction.

・Fix the cable so that the sensor, the base of the sensor, and thecable itself are not shaken or shocked.

・As with other electronic devices, inrush current may be generated when the system starts up, so please set the power
supply in consideration of the inrush current.

(Fig. 2) Cable bending radius・Since metal overheating and internal elements may be damaged,
install the base part so that it does not face metal, and thenturn on the power. (Fig. 3)

・ If foreign matter get inside the device from the end of the cable,
it may cause fire, smoke, fire, electric shock, or malfunction due tomalfunction or short circuit. (Fig. 4)(Fig. 3)

Foreign material

・Design the system so that the entire system works safely even if the external power supply is abnormal or the product fails.
・Please be careful about the influence on the material degradation due to the installation environment and the intrusionof foreign material. Especially when using it outdoors, please install it with less influence from ultraviolet rays.

noise((+_+))

・ If you are in an abnormal condition such as smoke, abnormal noise, or strange odor, discontinue use immediately as there
is a risk of malfunction, fire, electric shock, or accident.

Power lines and high-voltage equipment

・To avoid damaging the product due to abnormal heat generation, do not hold the transmission distance/ center offset / overload condition outside the specifications for a long time.

・Be sure to use accessories and specified parts. If you do not use it, it may cause malfunction, accident, malfunction, fire, etc.

・ Impact and external noise may cause malfunction or failure. Route the cable away from power lines and high-voltage
equipment without giving a shock. (Fig. 5)

・If you add or move equipment, please check the installation conditions again.

・Make sure that the total current consumption of the connected devices does not exceed the output current value.
・In order to consider and reduce the self-heating of this product, take measures so that it can be used below the specified ambient
temperature.

・When disposing of this product, dispose of it as industrial waste.
・Please note that the contents and specifications of this manual are subject to change without notice.
If you have any questions about the contents of this manual, please contact us.

・To reduce the effect of self-heating (heat dissipation), it is recommended to mount it on metal using case mounting screws.

■ Standards and regulations

・If it is installed in a place where it is exposed to direct sunlight or hot air from a heater, it may cause a fire or malfunction. (Fig. 6)

・The control communication device installed in the product corresponds to a "weak radio station(weak radio wave device)",so the Minister of Internal Affairs and Communications' radio station permit (diploma) is not required.
However, please be careful when operating it as it may affect electronic devices and medical devices(pacemakers, etc.).

・If you apply power to the remote part or energize either one with the base part sections facing each other, a failure mayoccur. (Fig. 7)・Please use in an environment where it is not exposed to organic solvents or liquids containing them. (Fig. 8)(Fig. 6)(+_+)
