Passive Infrared Sensors

Manufacturer: Bircher Reglomat
Category: Passive Infrared Sensors

Passive Infrared Sensors detect persons or objects, which have a surface temperature difference of at least +/- 2°C compared to that of the scanned zone and which are moving at a rate of at least 10cm per second. Both movement and temperature difference are required for detection.


Passive Infrared Sensors are used for the activation of Automatic Pedestrian Doors. This technology has been successful where other types of sensors have been troublesome. These sensors are not vulnerable to wind blown debris, extraneous radio signals or adverse weather conditions.
