## Description

This inductive ring proximity sensor detects metal objects as they enter or pass through a 22 mm ring opening. Operating on a 6–36 V supply with NPN normally-open output, it delivers a sub-1 ms response time — fast enough to reliably detect small, fast-moving metal parts. The sensor features an onboard LED that lights up when a metal object is detected, plus an adjustable sensitivity knob for fine-tuning. Its brass nickel-plated, flame-retardant housing is sealed to IP66, making it suitable for both indoor and outdoor use in temperatures from −25 °C to 65 °C. Key Features 22 mm Ring Opening – Detects metal objects passing through the ring Fast Response – Less than 1 ms switching time at up to 300 Hz Wide Voltage Range – 6–36 V DC input NPN Normally-Open Output – Up to 300 mA current capacity 10 mm Detection Distance – Reliable sensing range for metal objects Adjustable Sensitivity – Onboard knob (clockwise to increase) LED Status Indicator – Visual confirmation of detection IP66 Rated – Dust-tight and protected against powerful water jets Rugged Construction – Brass nickel-plated, flame-retardant housing 2 m Wire Lead – Pre-wired for easy installation Specifications Supply Voltage: 6–36 V DC Output Type: NPN (normally-open), high/low level signal Max Current: 300 mA Hole Diameter: 22 mm Detection Distance: 10 mm Switch Frequency: 300 Hz Operating Temperature: −25 °C to 65 °C Operating Humidity: 35–95% RH Dimensions: 68 × 39 × 20 mm Ideal For Counting or detecting small metal parts (screws, washers, nuts) Monitoring wire breakages and jams Industrial automation and conveyor systems Quality control on production lines Package Contents 1× Ring Inductive Proximity Sensor (22 mm Hole Diameter)
