Tower Beams


The PXB-100ATC-KH photoelectric beam sensor is designed specifically for use in our TA Series 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.


Requires TAKH ‘Quick-fix’ mounting brackets for fast, trouble-free installation; the beam units locate in vertical slide-channels in the TA tower spine, allowing easy and precise height adjustment.
