Battery powered quad beam TXF-125-KH

The TXF-125-KH is a battery operated quad beam sensor for use in beam towers, compatible with leading wireless systems. It reduces the time and cost of permanent installations and allows 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.
