Mini Inductive Sensor Switch Stainless Steel IP65 Waterproof Proximity Switch with 2m Cable M3 M4 M5 M6 Three Wire NPN PNP Sensing distance: 1mm Load current: 100mA Working voltage: 10-30VDC Response time: 0.5ms Protection grade: IP65 Operating frequency: 1kHz Operating temperature: - 25 ~ 70 NPN: indicates common positive voltage and output negative voltage PNP: indicates common negative voltage and outputs positive voltage NPN NO: Normally, it is normally open. When materials are detected, the black line outputs a negative pressure signal NPN NC: Normally, it is normally closed, and the black line outputs negative pressure signal. When the material is detected, the signal is disconnected PNP NO: Normally, it is normally open. When the material is detected, the black line outputs a positive pressure signal PNP NC: Normally, it is normally closed, and the black line outputs a positive pressure signal. When the material is detected, the signal is disconnected _x000D_
