High security anti-crawl beam PXB-100ATC-KH

The PXB-100ATC-KH photoelectric beam sensor is designed specifically for use in beam towers for high-risk applications where detection of all intrusion attempts is critical. Sophisticated dual response output systems have been designed to distinguish and allocate specific alarm responses based on the size and speed of target objects moving through the detection area, and a unique synchronized timing system ensures unrivalled detection performance and versatility.


TAKEX KH series beams and Bunker Seguridad towers are a reliable combination for perimeter intrusion detection.

For distances up to 100m (330ft) outdoor and up to 200m (660ft) indoor.


  • Independent control of upper and lower beams
  • Double coated electronics for demanding environments
  • Choose between synchro-quad and anti-crawl operation
  • Dual outputs for crawl attempt and full beam break
  • Sync wire allows unlimited stacking without crosstalk
  • 4 selectable beam channels
  • Increased beam separation minimises nuisance alarms
  • Vivid internal colour aids beam alignment procedure
  • Lightning and surge protection up to 15kV
