Ring Inductive Proximity Sensor (22mm Hole Diameter)

Inductive Ring Proximity Sensor (22mm Hole Diameter) is engineered for reliable detection of metal objects passing through a circular sensing zone. This ring-style inductive detector identifies screws, washers, nuts, wires, and other conductive components moving through the aperture without physical contact. A wide 6–36V operating voltage allows easy integration with industrial control systems and automation equipment. Fast response performance below 1ms enables accurate detection of small, high‑speed metal parts, while the adjustable sensitivity dial supports precise tuning for different detection environments. Rugged brass nickel‑plated housing combined with IP66 protection ensures dependable operation in demanding indoor or outdoor installations.

High-Speed Metal Detection

This ring-type inductive sensing module achieves a response time under 1ms and supports switching frequencies up to 300Hz, enabling accurate monitoring of fast-moving metallic objects. Precision electromagnetic sensing ensures stable detection even for small components such as screws or washers passing rapidly through the aperture. Such responsiveness makes the metal detection ring suitable for automated production lines, wire monitoring systems, and mechanical motion tracking where missed triggers can interrupt operations.

Adjustable Sensitivity with Visual Status Indicator

An integrated sensitivity adjustment knob allows fine-tuning of detection performance according to object size, material, and installation distance. Clockwise rotation increases sensitivity for smaller metal targets or higher-speed conveyor systems. An onboard LED indicator provides clear real-time feedback by illuminating whenever metallic material enters the sensing field. This visual status signal simplifies installation, calibration, and troubleshooting in industrial automation setups.

Rugged Industrial Construction

Brass nickel‑plated flame‑retardant housing protects the inductive detection unit from corrosion, mechanical wear, and electrical interference. IP66-rated sealing ensures resistance against dust and water exposure, allowing reliable deployment in factory environments or outdoor monitoring systems. Operational stability across a temperature range of -25℃ to 65℃ supports long-term installation in demanding environmental conditions such as workshops, warehouses, and automated machinery enclosures.

This inductive metal detection ring is widely applied in automation and safety monitoring tasks such as detecting small metal fasteners, identifying wire breakage, sensing jam conditions in feeding systems, and monitoring moving metallic components within mechanical equipment.
