Mounting

Sensor alignment
Position the device in a way that the distance to the object is within the working range of the sensor.
Screw the sensor to the mounting bracket, e.g. type OMH­VDM18­01 (not included in delivery) or a suitable device
(torque max. 2 Nm). Only use the holes provided in the housing (see dimensioned drawing page 3) for this purpose.
If steps, moving or striped objects are to be detected, the front panel of the sensor should be mounted at a right
angle to the direction of movement or stripes (Illustr. 5 + 6).
With very reflective objects, the sensor must be mounted at an angle of approx. 5° (Illustr. 7).
To optimise measurements, the distance sensor is to be given constructive protection from
vibrations.
The device is now mounted.
