M12 4-pin laser distance sensors use a visible red or infrared laser for high-precision distance measurement or presence detection at longer ranges than standard photoelectric sensors.
| Pin | Name | Function | Type |
|---|---|---|---|
| 1 | VCC | Supply voltage 10-30V brown | PWR |
| 2 | OUT2 | Second output white | I/O |
| 3 | GND | Ground blue | GND |
| 4 | OUT1 | Primary output analog or digital black | ADC |
