The TXF-125E and TXF-125DM are battery operated quad photoelectric beam sensors 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. Powered by 3.6V (17Ah) batteries and featuring ±90° horizontal/±20° vertical adjustable optics to cater for the most dynamic of terrains. 4 x Synchronised high power beams Four selectable operation ranges 25/50/75/100m 4 x Selectable beam channels to prevent crosstalk Vivid internal colour aids beam alignment procedure ±90° horizontal ±20° vertical adjustable sensor heads Environmental monitoring circuit IP65 housing
