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

PXB-HF-KH series beams are 4-channel quad beams designed specifically for use in beam towers. They include environmental monitoring circuit for maximum stability in severe weather conditions, perfect for long range perimeter intruder detection.


PXB-HF-KH series beams provide 4 selectable beam channels to prevent crosstalk.

  • PXB-50HF-KH: 4 x synchronised high power beams. Range: up to outdoor 50m / 100m indoor.
  • PXB-100HF-KH: 4 x synchronised high power beams. Range: up to outdoor 100m / 200m indoor.
  • PXB-200HF-KH: 4 x synchronised high power beams. Range: up to outdoor 200m / 400m indoor.

More features:

  • Double coated electronics for demanding environments
  • Double modulation for unsurpassed light immunity
  • Increased beam separation minimises nuisance alarms
