Ring Inductive Proximity Sensor (3mm Hole Diameter) SF_Arduino Boards Voltage and Current Control enablesThese Inductive Ring Proximity sensors are designed to detect metal objects entering or passing through the ring. They operate on a 6 36V power supply and offer NPN output. The sensor features less than 1ms response time, high accuracy, and stable performance, which could work well even in the detection of fast moving small metal objects. It comes with onboard LED for indicating detection status(light up when metal object detected) and sensitivity
