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 ac
-
cordance with its intended
