Instructions● Do not use the proximity switch at voltages and currents that exceed its "Specifications" (see page J-71). If the voltage or current is too low, theoperation indication light may not light up. Use within the range of "Specifications".
● Electrical Conduit Connection●When wiring to the proximity switch, be sure to turn off the power to the electrical circuit on the connection side before proceeding.

●When wiring switches for DC, pay close attention to the polarity (color of lead wires and plus/minus terminal positions of connectors) andconnect them correctly. If the wiring is reversed the operation indication light will not light.
●When using a cabtyre cord for wiring to the connector type, use a JIS C 3306 VCTF 0.3 to 0.75 ㎟ 2-core, outer diameter 4 to 6 mm or less. For
lead wires type, use cabtyre cords of 0.3 to 0.75 ㎟ or less.
● Cylinders with proximity switches use magnetic and electronic components, and should not be used at ambient temperatures above 70°C due totheir temperature characteristics. Use hydraulic fluid within both viscosities of 20 to 400 ㎟/s and temperatures of -10 to +60°C.
● The proximity switch may malfunction in locations where there is a strong magnetic field or high current in the surrounding area (e.g., spot
welders). In such cases Use an iron plate or other magnetic material to block the magnetism.
● When using multiple cylinders with proximity switches in close proximity, provide a distance of at least 30 mm between the switch and the othercylinders to avoid the influence of the magnet built into the piston.
● Avoid use the proximity switch in locations where the cylinder body is buried in iron or magnetic chips, as this may cause the proximity switch tomalfunction.
● Since a magnet is used in the cylinder piston section, it may be affected by iron powder in the hydraulic system. We recommend installing a microseparator (Model No. MGB-260, etc.) in the hydraulic tank to remove such iron powder.

For other instructions, refer to "instructions" pages J-4 to J-7.

"CJT" Series Hydraulic Cylinders with Proximity Switch

Actuators"CJT" Series Hydraulic Cylinders with Proximity Switch● The detection position of the cylinder can be set arbitrarily and easily by adjusting theposition of the slide type proximity switch on the cylinder body.
● The position sensing device attached to the machine body is no longer necessary, which
reduces the man-hours required for design and assembly and also makes the equipment
more compact.
● Proximity switches are available in lead wire and plug-in connector types, which can beselected according to the application. The lead wire type is available in 1.5 m (standard)and 5 m lead lengths.

■ Structure and Operation
When the cylinder piston moves and is positioned below theproximity switch, the magnetic field generated by the magnet built
into the piston activates the switch to detect the cylinder stroke
position.

1. When ordering a proximity switch ass'y including bracket, please
specify according to the following.

1. The switch can be mounted on any tie rod. Mounting the switch inthe most suitable location according to the mounting space andwiring method of the cylinder.
2. Loosen the two set screws securing the bracket on which the switch
is mounted with an Allen wrench, and move the switch along the tie
rods.
Refer to the table below for set screw sizes.
3. For position detection at the stroke end, adjust the position referringto the SS dimensions in the outline dimension drawing on theprevious page.
For position detection at the mid-stroke, adjust the position so thatthe switch indicator light starts to turn on at the desired position.
4. Press down lightly on the top surface of the switch with your finger
and tighten the set screw while the cylinder tube is in contact withthe detection surface of the switch. Refer to the table below for theproper tightening torque for the set screw.
Note: If the tightening torque is not appropriate, the switch may bemisaligned.
