Detection of glossy surfaces within the operating range
When detecting glossy surfaces (e.g. metals), the light beam should not hit the ob-
ject surface at a right angle. A slight inclination is enough to detect the object reli-
ably. The following applies: the smaller the scanning range, the greater the angle
of inclination (approx. 5 ° to 7 °).
1
A Slight inclination 5 ° ... 7 °
B Glossy object surface within the scanning range
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).
NOTICE
It is imperative to note the task and the associated inclination of the
sensor of approx. 5 ° ... 7 ° .

A Slight inclination 5 ° ... 7 °
B Glossy surface in the background
C Scanning range limit
– 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.
