NPN/PNP NO Slot Type Sensor E3S-GS30C1 Photoelectric Switch

Groove width distance:30mm; Application:The direction judgment of the crane and the detection of the approach into the dangerous zone Dimension:20*55*72

Operation principle of photoelectric switch:The transmitter aims at the target and generates a light beam, and the receptor turns the light energy received into current and transmits it to the detection circuit backward. It can filter out an effective signal and use it.
