Position detection unit (option)
Three types of position detection units can be built in at most.
Micro switch: 4 pieces.
Potentiometer: 1 pc.
Rotary encoder: 1 pc.
Structure
Following shows the unit diagram consisting of micro switch, potentiometer and rotary encoder.
∎
Note
1. Newly delivered micro switches have already been tested, but have not been adjusted for stroke.
Therefore, you must carry out stroke adjustment after the unit is installed. Be sure to take into
consideration the inertia of the jack when performing the stroke adjustment. If the travel screw is
turned while the input shaft fixed after adjustment, the adjusted settings will change. Therefore, do
not allow the travel screw to be turned (for traveling nut-types, do not allow the nut to be turned).
2. Position detection unit consists of precision parts. Never apply shock or vibration.
3. Never rotate LS cam strongly after fixing it by the set of screws. Otherwise, built in reducer can
brake.

Connection
1. Use the terminal block in the unit for the connection to each detector. Connection of each detector
to terminal block is previously completed.
2. In case of long distance wiring, signal loss can get worse.
3. Make sure to ground the shield wire of the detector unit and signal.
4. Locate the signal and power line separately. Put noise filter, shield the signal line, in case there is
a source of noise. Use shield wire for wiring rotary encoder.
5. Use suitable diameter of cable, which corresponds to the connector of position detection unit. In
case of smaller diameter cable or bulk cable, waterproof is poor.
Applicable cable diameter: SCL14B (12.5 to 14.5 mm dia.)
6. In case of wiring in rain or other wet environment, avoid water from entering the position detection
unit. It will damage the product.
