Ring Inductive Proximity Sensor (22mm Hole Diameter, NPN, IP66)

The Ring Inductive Proximity Sensor is a specialised metal-detection device featuring a 22mm central aperture. Designed for parts counting, wire monitoring, and sorting mechanisms, it suits makers, engineering students, and automation builders requiring fast non-contact sensing.

22mm detection aperture

The sensor features a 22mm ring opening that enables continuous, non-contact detection of metal objects passing directly through the centre.

NPN normally-open output

Equipped with an NPN normally-open (NO) output configuration, the sensor easily interfaces with microcontrollers, PLCs, and digital control circuits.

Wide supply voltage range

The device operates on an input voltage range of 6V to 36V DC, ensuring compatibility with standard industrial and robotics power rails.

Sub-millisecond response speed

A fast response time of under 1ms ensures precise and reliable detection of high-speed metallic parts in automated systems.

IP66 rated rugged housing

The unit is built into an IP66-rated enclosure, providing robust protection against dust ingress and low-pressure water jets in workshop environments.
