Photoelectric anti-crawl beam PB-100AT-KH

Takex PB-100AT-KH anti-crawl beams are available for high-security applications to detect low-level or crawling intrusion, designed specifically for use in beam towers.


TAKEX KH series beams and Bunker Seguridad towers are a reliable combination for perimeter intrusion detection in the most demanding of situations. Quad beams are synchronised to maintain range and stability in severe weather, while rejecting ‘nuisance-alarms’ caused by birds, animals, or blown-litter. They also provide trouble-free assembly as well as an easy and precise height adjustment.

These anti-crawl beams are suitable for distances up to 100m outdoor or up to 200m indoor applications.


  • Independent activation of upper or lower beams
  • Double coated electronics for demanding environments
  • Supplied with ’Quick fix’ mounting brackets for easy adjustment
