Application notes
 Detection of glossy surfaces within the scanning range:
When detecting glossy surfaces (e.g. metals), the light beam should not hit the object surface at a right angle. A
slight inclination is enough to detect the object reliably. The following applies: the smaller the scanning range, the
greater the angle of inclination (approx. 5° to 7°).
 Avoiding interference from glossy surfaces
in the background:
If a glossy surface is in the background (distance larger than scanning range limit), reflections may cause interfering
signals. They may be avoided by mounting the device at a slight inclination (see figure below).
Attention!
It is imperative to note the task and the associated inclination of the sensor of approx. 5° … 7°.
 Objects should only be moved in laterally from the right or left. Moving in objects from the connector side or oper-
ating side is to be avoided.
 Outside of the scanning range, the sensor operates as an energetic diffuse reflection sensor. Light objects can still
be reliably detected up to the scanning range limit.
 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.
