Application notes

– Objects should only be moved in laterally from the right or left. 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.

Detection of glossy object surfaces within the operating range
When detecting glossy object 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.

Opposite mounting of multiple sensors of the same type must ab-
solutely be avoided.
It is imperative to note the task and the associated inclination of
the sensor of approx. 5 ° ... 7 ° .
