Twin Photoelectric Beams

Takex PB-HF-KH Intelligent Quad Beams are designed specifically for use in Takex TA Series Beam Towers. Unique Quad beams are synchronised to maintain range and stability in severe weather, while rejecting ‘nuisance-alarms’ caused by birds, animals, or blown-litter.

Supplied with PTKH ‘Quickfix’ mounting brackets for fast, trouble-free assembly, the beam units locate in vertical slide-channels in the TA tower spine, allowing easy and precise height adjustment.

Takex KH Beams and TA Towers are the perfect combination for reliable perimeter intrusion detection in the most demanding of situations.

For distances up to 50m (165ft) outdoor / 100m (330ft) indoor.
