Use on revolving doors
The PIR 20 detects people and objects within the detection zone straightaway based on their temperature, then causes the revolving door to start moving.
Passive infrared motion detector for automatic doors, industrial doors and passenger lifts
PIR 20 detectors themselves do not emit any rays. As soon as the infrared detector identifies an object whose surface temperature differs from its environment, the object's thermal radiation is routed via lenses to detector elements and the switching operation is triggered.
The PIR 20 contains 12 fresnel lenses, which are installed in the housing cover directly. Thanks to its compact dimensions, it can be integrated extremely well and allows for precise field adjustment.
