Genuine Panasonic EX-22B (Ultra-compact Photoelectric Sensor EX-20 Ver.2): Ultra-compact Photoelectric Sensor, Diffuse reflective, NPN.
This sensor switches its output when the light beam is interrupted or reflected by the object; its small housing allows it to be fitted where larger sensors do not fit.
