Ring Inductive Proximity Sensor (15mm Hole Diameter)

Ring Inductive Proximity Sensor (15mm Hole Diameter) provides reliable non-contact detection for metal objects moving through a circular sensing field. Designed for industrial automation and equipment monitoring, this inductive ring detector operates on a wide 6–36V supply and delivers stable NPN normally‑open output signals. Fast switching performance below 1ms enables accurate tracking of small or high‑speed metal parts such as screws, washers, and nuts. A rugged brass nickel‑plated flame‑retardant housing combined with IP66 protection ensures dependable operation in demanding indoor and outdoor environments including dusty workshops and production lines.

High‑Speed Metal Detection

This inductive ring detection module delivers response times under 1ms and supports switching frequencies up to 300Hz, enabling reliable monitoring of rapidly moving components. The circular sensing structure allows metal parts to pass through the detection field without requiring precise alignment. Such characteristics make this metal detection ring particularly suitable for automated machinery, assembly equipment, and conveyor‑based inspection systems where small conductive components move at high speed.

Adjustable Sensitivity with Visual Status Indicator

An integrated sensitivity adjustment knob allows fine‑tuning of the detection threshold by simple clockwise rotation. This feature helps adapt the sensing range for different metal sizes or installation environments. An onboard LED indicator clearly displays the detection state, illuminating whenever a metal object enters the sensing zone. This visual feedback simplifies system setup, troubleshooting, and calibration during installation in industrial or laboratory environments.

Industrial‑Grade Protection and Durable Construction

A brass nickel‑plated flame‑retardant enclosure provides strong resistance to corrosion, mechanical wear, and harsh environmental conditions. The sealed structure achieves IP66 protection, shielding internal electronics from dust and water exposure. With an operating temperature range of -25℃ to 65℃ and stable performance under 35–95% humidity, this inductive sensing unit remains reliable across outdoor installations, factory floors, and long‑term monitoring systems.

Typical applications include detection of screws, nuts, and washers in automated assembly lines, monitoring of wire breakage or material jams in production equipment, and metal object counting within mechanical systems. The ring‑style inductive sensor offers a compact and efficient solution for industrial automation, process monitoring, and equipment protection where consistent metal detection is required.
