PIR 20 & PIR 30

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.

The PIR 30 passive infrared motion detector itself does not emit any beams. It detects objects whose surface temperatures differ from their environment. As soon as these objects enter the motion detector's detection zone, their thermal radiation is routed via lenses to detector elements. This detection process triggers the switching operation.

18 fresnel lenses are installed in the front cover directly. These lenses create an invisible carpet over the detection area, which can be adjusted precisely and almost however the user likes.
