Wiring diagram
With retro-reflective sensors, emitter and
receiver are incorporated in one compact
housing. The light beam of the emitter is di-
rected towards a reflector which returns
the light back to the receiver. An object is
detected when it interrupts this beam. Re-
tro-reflective sensors have a high function
gain and good contrast performance. Fur-
ther it is merely required to install and wire
a single device.
