Remarks
With the set scanning
range, a tolerance of the
scanning range limits is
possible depending on the
reflection properties of the
material surface.
Operate in accordance with
intended use!
This product is not a safety sensor
and is not intended as personnel
protection.
The product may only be put into
operation by competent persons.
Only use the product in accor-
dance with the intended use.
