NOTICE
It is imperative to note the task and the associated inclination of the
sensor of approx. 5 ° ... 7 ° .
– Only move objects in from the right or left side. Avoid moving in objects from
the connector side or operating side.
– Outside of the scanning range, the sensor operates as an energetic diffuse
reflection sensor. Light objects can still be reliably detected up to the scan-
ning range limit.
– The sensors are equipped with effective measures for the maximum avoid-
ance of mutual interference should they be mounted opposite one another.
Opposite mounting of multiple sensors of the same type must absolutely be
avoided.

Object detection behind diaphragms
It is sometimes necessary to mount the sensor behind plant parts so that the light
beam has to pass through an opening (diaphragm) that is as small as possible.
Here, the detection depends, among other things, on set scanning range t
tance a between diaphragm and sensor, and diaphragm diameter d. Here are
some reference values:
NOTICE
Reference values are not guaranteed properties. Due to the multitude
of possible influencing factors, they must be confirmed in the applica-
tion.
