WebSep 13, 2024 · A diffuse-reflective sensor expects the light to be reflected by the object while retro-reflective sensors expect the light beam to be interrupted by the object to detect it. Retro-reflective sensors also need a dedicated retroreflector to function. WebThe operating principle is the transmitting and receiving of light in an optical sensor, the object to be detected reflects or interrupts a light beam sent out by an emitting diode. Depending on the type of device, the interruption or reflection of the light beam is evaluated.
