Ring Inductive Proximity Sensor (3mm Hole Diameter)

The Ring Inductive Proximity Sensor is a compact industrial-grade sensor featuring a 3mm sensing aperture for metallic object detection. Delivering quick NPN normally-open output across a 6-36V supply, it is ideal for makers, engineering students, and hobbyists building automated counting or sorting mechanisms.

3mm internal sensing ring

The unit features a 3mm aperture ring designed to detect metallic objects and targets as they pass through the centre.

Wide 6-36V operating voltage

This sensor accepts a direct current input ranging from 6V to 36V, allowing seamless integration with industrial control equipment and maker development boards.

NPN normally-open switching

Equipped with an NPN NO (normally-open) output, the sensor pulls low upon detection to interface easily with microcontrollers, PLCs, and logic circuits.

Sub-millisecond response time

A response time of less than 1ms enables fast, dependable signal triggering for high-speed inline sorting and automated counting applications.

Durable IP66-rated housing

Built within an IP66-rated enclosure, the sensor resists dust ingress and water exposure in demanding workshop and industrial environments.
