Application notes
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 range, the greater the angle of inclina-
tion (approx. 5 °to7 °).

B Glossy object surface within the operating range
Avoiding interference from glossy surfaces in the background
If a glossy surface is in the background (distance larger than maximum range), re-
flections may cause interfering signals. They may be avoided by mounting the de-
vice 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 °.

– Only move objects in from the right or left side. Avoid moving in objects from
the connector side or operating side.
– Outside of the operating range, the sensor operates as an energetic diffuse
reflection sensor. Light objects can still be reliably detected up to the maxi-
mum range.
– 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.
