Battery Operated


The TXF-125E-KH is a battery operated quad photoelectric beam sensor for use in TA series Beam Towers, designed for compatibility with leading wireless systems; reducing the time and cost of permanent installations and allowing the use of Active Infrared Beams on rapid deployment or temporary installations.

With 4 selectable frequencies, multiple beam sets can be used in both linear and stacked configurations without risk of crosstalk, further assisted by a transmitter power function that allows the user to set 25/50/75/100m zones.

Two 3.6V (17Ah) batteries can power each unit for approximately 5 years of service, and ±90° horizontal/±20° vertical adjustable optics cater for the most dynamic of terrains.


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.
