Sensor OFF
In the areas between "Sensor OFF"
and the operating range, the sensor
functions with only a low performance reserve. The sensor typically
flashes in this case. Depending on
the tolerance, it is, however, also
possible that the sensor no longer
detects objects.

Remarks
z Approved purpose
The diffuse reflection light scanners are optical electronic sensors for optical, contactless detection of
objects. This product may only be used by qualified personnel and must only be used for the approved
purpose. This sensor is not a safety sensor and is not to be used for the protection of persons.

Application notes
z When detecting glossy surfaces (e.g. metals), the light beam should not be incident on the object surface at a right angle.
A slight inclination is sufficient for preventing undesired direct reflections. The following rule of thumb applies: the smaller the
scanning range, the larger the angle of inclination (approx. 5  7).
Slight inclination
5  7
Glossy object surface
z Objects should only be moved in laterally from the right or left. Moving in objects from the cable side or LED side is to be avoided.
z The sensors are equipped with effective measures for the maximum avoidance of mutual interference should they be mounted
opposite one another. Opposite mounting of multiple sensors of the same type should, however, absolutely be avoided.
