Wiring Diagram (3-Wire DC Sensor)
Standard cable wiring configuration:
Brown → +V (10–30 VDC)
Blue → 0V (GND)
Black → Output signal
The sensors support PNP or NPN output wiring depending on model configuration.
Sensitivity Adjustment
The DSCP series sensors include an adjustable potentiometer for sensitivity control:
- Remove the target from the sensing area.
- Rotate the potentiometer clockwise until the output turns ON.
- Place the target at the desired sensing distance.
- Rotate counterclockwise until the output turns OFF.
- Set the midpoint for stable detection.
For reliable operation, the recommended difference between ON and OFF positions is ≥ 1.5 turns.
