Genuine Panasonic CX-421 (Compact Photoelectric Sensor CX-400 Ver.2): Compact Photoelectric Sensor, Diffuse reflective, 300 mm, 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.
