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.
