7 Blue Ground
8 Shield Shield/drain wire*
* The shield/drain wire is connected internally to the sensor housing and should be connected as follows:
1. If the sensor housing is mounted so that it is in continuity with both the machine frame and earth ground, connect the shield/
drain wire (also) to earth ground.
2. If the sensor housing is mounted so that it is insulated from the machine frame, connect the shield/drain wire to -V dc (together
with the blue wire).
3. If the sensor is mounted so that it is in continuity with the machine frame, but not with earth ground, do not connect the
shield/drain wire (i.e. cut off the shield/drain wire).
2.2 Installation
The LH Series Laser Displacement Sensor is an optical instrument capable of micrometer-level resolutions.
Note: Handle the sensor with care when installing and operating. Applications requiring measurement resolution in the
micrometer range must take vibration, dust, and thermal expansion effects into consideration. Windows of all sensors must be
clean for full functionality. Windows that are soiled by dust, water, oil, etc may cause the sensor to not operate correctly. The
windows should be cleaned thoroughly whenever necessary, using a high quality glass cleaner.
2.2.1 Displacement Measurement Installation
1. Adjust the distance between the sensor head and the target so the target is near the middle of the measurement range.
2. The sensor must be aligned to the target so the laser beam strikes the target surface at a right angle.
3. Secure the sensor with 3 bolts of 4 mm diameter.
4. Attach the M12 cord set and complete wiring of the sensor.
