Inductive Proximity Sensor 12mm NPN

Inductive Proximity Sensor 12mm NPN in Lahore Pakistan

Product Details – 12 mm Inductive Proximity Sensor (NPN)

General Description

A 12 mm inductive proximity sensor is a rugged, non-contact switch commonly used to detect metallic objects. It typically:

• Has a 12 mm threaded (M12) cylindrical housing,

• Uses electromagnetic induction to sense targets,

• Offers NPN (sinking) output, often as Normally Open (NO).

These sensors are widely used for automation, counting, position detection, and machine safety functions.

How to Use This Sensor

1. Installation

• Mounting: Thread into an M12-compatible hole; use nuts to secure flush or non-flush orientation.

• Shielding: Choose shields (2 mm) or unshielded (4 mm) based on the required sensing range and mounting proximity to metal surroundings.

2. Wiring

Typical 3-wire NPN configuration:

• Brown → +V (10–30 V DC)

• Blue → 0 V (Ground)

• Black → Output (goes to ground when target detected)

3. Operation

• On power-up, bring a metal object within sensing distance; the sensor activates (LED lights), and the output sinks current (NPN behavior).

• Ideal for interfacing with PLC inputs, relays, or control circuits.

4. Applications

• Detecting presence on conveyor systems or industrial equipment.

• Position feedback in automated machinery.

• Replacing mechanical limit switches for high-reliability systems.

• Integration in packaging, robotics, and counting systems.
