WebPhotoelectric sensors that detect the distance, absence, or presence of an object; Function. An optical sensor converts light rays into electronic signals. It measures the physical quantity of light and then translates it into a form that is readable by an instrument. An optical sensor is generally part of a larger system that integrates a ... WebSep 13, 2024 · A diffuse photoelectric sensor, also known as diffuse-reflective sensor is an optical proximity sensor. It uses the principle of reflection to detect objects in its sensing range. The sensor has a light source and a receiver housed in the same package. The light beam is emitted towards the target/object and reflected back to the sensor by the ...
