PIR 20 Passive Infrared Motion Detector PIR 20

PIR 20 – Passive Infrared Motion Detector Function / Adjustments / Mounting Function PIR Motion Detectors do not emit any rays as indicated by their name Passive Infrared Motion Detector. When an object with a surface temperature other than that of the environment enters the detection area, its heat radiation is directed via lenses on sensor elements and triggers a switching operation. Benefits of the PIR 20 Fig. 1 Mounting height 2 m • Excellent possibilities for integration due to small dimensions (see fig. 3) Zoom Position Window for Fresnel lenses Pos. 10 Pos. 0 Field adjustment PIR 20...
