Ring Inductive Proximity Sensor (12mm Hole Diameter, NPN, IP66)

This industrial ring inductive proximity sensor features a 12mm sensing aperture designed for non-contact detection of passing metal objects. It is well suited to students, makers, and automation developers building parts-counting mechanisms or material-handling systems. With rapid triggering and robust enclosure protection, it provides reliable performance across a range of prototyping and machinery projects.

12mm ring sensing aperture

The circular 12mm through-hole allows metal components, fasteners, or wires to pass directly through the active sensing zone. This ring-style geometry enables clean detection without requiring physical contact or surface mounting at the target.

NPN normally-open output

Featuring an NPN normally-open switching configuration, the sensor interfaces seamlessly with common digital logic, PLCs, and microcontroller inputs. This provides straightforward wiring for automated control and counting systems.

Wide 6 to 36V input range

The unit operates across a broad direct-current supply voltage of 6V to 36V. This wide tolerance accommodates standard industrial power rails as well as typical benchtop robotics power supplies.

Fast sub-millisecond response

A response time of under 1ms ensures the sensor registers rapid pass-through events accurately. This high-speed performance makes it suitable for high-throughput sorting, cycle tracking, and speed-sensing applications.

Durable IP66-rated enclosure

Constructed with an IP66-rated housing, the sensor is protected against dust ingress and powerful water jets. This resilient design ensures long-term operational stability in dusty workshop or industrial environments.
