A photoelectric proximity sensor, also known as a photoelectric sensor or photoelectric switch, is a type of sensor used to detect the presence or absence of objects, as well as their position or distance, based on the interruption or reflection of light. These sensors are widely used in industrial automation and control systems for various applications. Photoelectric proximity sensors operate by emitting a beam of light and detecting changes in that light caused by the presence or absence of an object.
