INSTRUCTION MANUAL
● It is dangerous to wire or attach/remove the connector with the power
on. Make sure to turn off the power before operation.
●Installing in the following places may result in malfunction:
1. A dusty or steamy place
2. A place generating corrosive gas
3. A place directly receiving scattering water or oil.
4. A place suffered from heavy vibration or impact.
●The product is not designed for outdoor use.
●Do not use the sensor in a transient state at power on（Approx. 15min.
Warm up period）
●Do not wire with the high voltage cable or the power lines.
Failure to do this will cause malfunction by induction or damage.
●Do not use the product in water.
●Operate within the rated range.
● Wipe off dirt on the emitting/receiving parts to maintain correct
detection. Also, avoid direct impact on the product.

Installation
Caution for connection
1) Connect the lead wires correctly. The analog output wire must not be in contact
with any other wire. Do not turn on the power while wiring.
2) The blue wire（0V） and shield wire（analog GND） are internally connected.
Use the blue wire（0V） for the power supply and use the shield wire（analog GND） for
analog output.
Install the sensor and adjust the light spot onto the measuring point so that the distance indicator turns ON ( orange ) at
the middle of measuring range.
Use M4 screw (tightening torque need to be under 0.8N･m).
・Adjust the sensor position so that it is set parallel to the surface of object obtain reliable measurement (see above).
・If there is any foreign object around the spot that is glossier than the measuring object, it may cause incorrect
measurement.
