M8 4-pin NPN proximity sensors output a sinking signal (pull to ground when active) for detecting metal objects. The M8 connector provides supply voltage, output signal, and ground in a compact IP67 sealed housing.
| Pin | Name | Function | Type |
|---|---|---|---|
| 1 | VCC | Supply voltage 10-30V brown | PWR |
| 2 | NC | Not connected white | I/O |
| 3 | GND | Ground blue | GND |
| 4 | OUT | NPN output signal black | I/O |
