A retroreflective sensor contains both the emitter and receiver in one housing. The light beam from the emitter is bounced off a reflector and detected by the receiver. The object is detected when it breaks this light beam. It has a longer sensing distance than a polarized sensor. Avoid using it for precise positioning control or detecting small parts.
