Wiring diagram
Functional principle
Retro-reflective sensors incorporate emitter
and receiver in a single compact housing. The
light beam of the emitter is directed towards
a reflector which returns the light back to the
receiver. An object is detected when it inter-
rupts this beam. Retro-reflective sensors in-
corporate some of the advantages of opposed
mode sensors (good contrast and high excess
gain). Further it is merely required to install
and wire a single device. A smaller sensing
range and susceptibility of devices without po-
larisation filter can be of disadvantage when
shiny objects have to be detected.
