Genuine Panasonic CX-442 (Compact Photoelectric Sensor CX-400 Ver.2): Compact Photoelectric Sensor, Adjustable range reflective, 40 to 300 mm, NPN.
Photoelectric sensors detect objects without contact by means of a light beam; thru-beam types (separate emitter and receiver) give the longest range and the most stable detection, while retroreflective and diffuse types need wiring on one side only.
