Photoelectric beams PB-50/100/200HF-KH

PB-xxHF-KH are 4-channel quad beams designed specifically for use in beam towers. They are easy to align and allow multiple beams to be used without ’cross-talk’ (interference).

Suitable for outdoor and indoor perimeter protection.


TAKEX KH series beams and Bunker Seguridad towers are a reliable combination for perimeter intrusion detection in the most demanding of situations. Supplied with PTKH ‘Quick fix’ mounting brackets for fast, trouble-free assembly, the beam units locate in vertical slide-channels in the tower column, allowing easy and precise height adjustment. Quad beams are synchronised to maintain range and stability in severe weather, while rejecting ‘nuisance-alarms’ caused by birds, animals, or blown-litter.
