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 incorporate some of
the advantages of opposed mode sensors
(good contrast and high excess gain). Fur-
ther it is merely required to install and wire
a single device. The smaller sensing range
and susceptibility to interference through
shiny objects when using devices without
polarisation filter can be disadvantageous
in some applications.
