Wenglor Retro K1R87PCT2 Reflex Sensor for Clear Glass Recognation

A reflector must be used in combination with these sensors. wenglor has the right retro-reflex light barrier for every application. Even crystal-clear objects and sheet products can be reliably recognized. The sensor is easy to install with its integrated M18 threaded fixation and can be easily protected as well. Time delay can be activated by RS-232 interface.


  • Dynamic readjustment of the switching threshold
  • Recognition of clear glass
  • Simple installation
  • Teach-in, external teach-in
