{"title":"Ring Inductive Proximity Sensor (22mm Hole Diameter)","handle":"ring-inductive-proximity-sensor-22mm-hole-diameter","url":"/products/ring-inductive-proximity-sensor-22mm-hole-diameter","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.\n\nThe 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.\n\nKey Features\n\n\n22 mm Ring Opening – Detects metal objects passing through the ring\n\nFast Response – Less than 1 ms switching time at up to 300 Hz\n\nWide Voltage Range – 6–36 V DC input\n\nNPN Normally-Open Output – Up to 300 mA current capacity\n\n10 mm Detection Distance – Reliable sensing range for metal objects\n\nAdjustable Sensitivity – Onboard knob (clockwise to increase)\n\nLED Status Indicator – Visual confirmation of detection\n\nIP66 Rated – Dust-tight and protected against powerful water jets\n\nRugged Construction – Brass nickel-plated, flame-retardant housing\n\n2 m Wire Lead – Pre-wired for easy installation\n\n\nSpecifications\n\n\nSupply Voltage: 6–36 V DC\n\nOutput Type: NPN (normally-open), high/low level signal\n\nMax Current: 300 mA\n\nHole Diameter: 22 mm\n\nDetection Distance: 10 mm\n\nSwitch Frequency: 300 Hz\n\nOperating Temperature: −25 °C to 65 °C\n\nOperating Humidity: 35–95% RH\n\nDimensions: 68 × 39 × 20 mm\n\n\nIdeal For\n\nCounting or detecting small metal parts (screws, washers, nuts)\nMonitoring wire breakages and jams\nIndustrial automation and conveyor systems\nQuality control on production lines\n\n\nPackage Contents\n\n1× Ring Inductive Proximity Sensor (22 mm Hole Diameter)\n","vendor":"DFRobot","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":2510,"title":"Default Title","sku":"DF-FIT0763","price":33.7,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
