Application notes

 Approved purpose:
This product may only be used by qualified personnel and must only be used for the approved purpose. This sensor is not a
safety sensor and is not to be used for the protection of persons.
 When detecting glossy surfaces (e.g. metals), the light beam should not be incident on the object surface at a right angle. A
slight inclination is sufficient for preventing undesired direct reflections. The following rule of thumb applies: the smaller the scan-
ning range, the larger the angle of inclination (approx. 5° … 7°).

Slight inclination
5° … 7°

Glossy object surface

 Outside of the scanning range, the sensor operates as an energetic diffuse reflection light scanner. 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.
