Battery Operated / TXF-125E-KH



up to 82ft
up to 165ft
up to 245ft up to 330ft

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 82/165/245/330ft 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.


  • specifically designed for use in TA series Tower Enclosures
  • 4 x synchronised high power beams
  • 4 selectable operation ranges 82/165/245/330ft
  • 4 selectable beam channels to prevent crosstalk
  • up to 5 year battery life using 2 x LS 33600 (3.6V 17Ah) batteries per unit
  • increased beam separation minimises nuisance alarms
  • vivid internal colour aids beam alignment procedure
  • ±90° horizontal ±20° vertical adjustable sensor heads
  • environmental monitoring circuit
