Notes
Glossy objects:
With glossy objects, the
sensor is to be fastened at
an inclination of
approx. 10° … 15° rela-
tive to the object surface.
Alignment aid:
An alignment aid is
included in the scope of
delivery of each sensor.
This facilitates simple
alignment of the sensor to
the working distance of 13
mm without needing to
perform electrical
commissioning.
Observe 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 its intended use.
