Infrared movement detector

These detectors are used to always keep the door handle in view and to initiate opening of the automatic swing door if needed. They react to changes in the incoming infrared radiation. Active infrared light sensors are outstanding for presence detection of persons and objects in situations with limited space. The scanning range can be adjusted using a mechanical adjustment screw. You can also use these sensors to check the number of people present in personnel and security interlocking door systems.
