Panasonic CX-444 – Compact Photoelectric Sensor, Adjustable range reflective, 20 to 100 mm, NPN. It belongs to the Panasonic Compact Photoelectric Sensor CX-400 Ver.2 series.
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.
