* In the following sections installation and setup are described using the example of the type
with front lens The functions of the units with side lens are identical
►
Align the diffuse reflection sensor to the object to be detected and secure it to
a bracket
Maximum range is only possible with precise alignment
►
Mount the unit so that the mounting position cannot change (avoid high
vibrations!).
Laser units with a very small light spot diameter are highly focussed; the
slightest change in the mounting position will result in misalignment
The optical position of the laser beam may deviate slightly from the mechanical
axis. Therefore we recommend using the fine adjustment units E20975 (front lens)
or E20976 (side lens) when mounting the laser units.
