Mount the DS900 Series Sensor
Firmly mount the sensor so that the laser is perpendicular to the motion of travel. The
accuracy and reliability of your 3D images relies on the three-dimensional coordinate
system defined by the position of the sensor and the movement of objects that pass
within its view.
The device has three (3) threaded M5 holes and can be mounted using 2 or 3 of
these holes, either as direct attachment points using M5 screws, or as through-holes
accommodating M4 screws. One of the mounting holes is a 3mm diameter reference
pin hole, provided to ensure accurate location of the unit during initial mounting or
replacement.
Note: The unit should be mounted such that the laser beam strikes the target
surface at right angles. Misalignment of the unit can result in inaccurate
measurements.
