Ring Inductive Proximity Sensor (22mm Hole Diameter)

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
