Panasonic EX-23 – Ultra-compact Photoelectric Sensor, Thru-beam, 2 m, NPN. It belongs to the Panasonic Ultra-compact Photoelectric Sensor EX-20 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.
