Active infrared intruder detector OPTEX Europe

Twin beam photoelectric sensors, designed for short-range outdoor or long-range indoor applications.

Using twin beams of pulsed infrared energy, reliable operation is possible in the worst conditions – up to 99% of the emitted radiation can be blocked by rain, fog or falling snow and the beams will still operate.

By utilising an automatic gain control circuit, gradual changes in signal strength caused by weather conditions are continually monitored and the trigger level adjusted accordingly to compensate. In addition, the unique anti-frost design allows for trouble-free operation when the cover is completely frosted over.
