RL81-54/25/76b/103/115

Product information "RL81-54/25/76b/103/115"

Version with test input and PNP output 

The RL81 was specifically developed for detecting people, objects, and vehicles at gates. Applications include gates in both outdoor and indoor areas and barrier systems.

A special universal wall mount has been developed for the RL81 for both side and front mounting.

The main features are the extreme reliability of detection on reflective surfaces at close range. Reliable suppression of vehicles or people passing very close to the sensor is enabled. This prevents false triggers and unwanted gate or barrier openings.

With energy-independent distance detection, reliable suppression is also possible on highly reflective surfaces or reflective films on work clothing.

2 mounting screws included

Test input function:

For the test, the transmitter is switched off at 0 V or open test input. Therefore, for operation, the operating voltage must also be applied to the test input (white)!
