This 100m photoelectric detector uses 4 pulsed infrared beams that are designed to activate an alarm only when 4 beams are simultaneously blocked.
The robust IP55 housing of the four photoelectric detectors is designed to provide reliable perimeter security both indoors and out. The transmitters emit invisible infrared beams to the receiver with changing frequencies to protect beams from disturbance.
