Inductive Proximity Limit Switch PL-05NB
NB = Normally Close
The Limit Switch PL-05NB is an inductive proximity sensor that detects metallic objects when they approach the sensor head without physical contact. This design minimizes wear and tear, extending operational life.
This model features NPN output and a Normally Close (NC) configuration, meaning:
- When no metallic object is near the sensor head, the circuit is in the “ON” state.
- When a metallic object approaches, the sensor will switch to the “OFF” state.
This configuration is ideal for applications requiring inverse signal logic (e.g., a signal that deactivates when an object is detected).

Wiring Guide
- Brown: Connect to +V (DC 10–30V)
- Blue: Connect to 0V (Ground)
- Black: Signal Output wire (connect to control circuit or PLC)
This NPN Normally Close model outputs a signal to ground (ON) when the sensor is not detecting an object. When an object is detected, the circuit is opened (OFF).
Operational Characteristics
- Operates on the principle of electromagnetic induction (Inductive Type).
- Detects only metallic objects; does not respond to non-metallic materials such as plastic or wood.
- Features an LED indicator on the sensor for immediate operational status verification.
Recommended Applications
- Detection of metallic objects in automated machinery.
- Limit switch functionality for robotic arms or conveyor systems.
- Position control in CNC machines, milling machines, and lathes.
- Metal object detection applications.
- Integration with PLCs or general controllers in automation systems.
