Photoelectric Beams PB-IN-100AT TAKEX

Bunker perimeter solution description: 

The PB-IN-100AT is designed with high security applications in mind, where attempts to crawl through a portion of the beam result in an alarm condition. Through CPU processing, the upper receiver selects the beam from the upper transmitter and the lower receiver selects the beam from the lower transmitter, creating an AND/OR-gated type detection system.
