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 interrupts this beam. Retro-reflective sensors incorporate 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. The smaller sensing range and susceptibility to interference through shiny objects when using devices without polarisation filter can be disadvantageous in some applications.
