It switches a PNP-NC output when a ferrous object enters the 2.1 mm sensing zone — that is a short-range, precision detect for small parts or end-of-stroke confirmation on compact actuators. Rated for 12 to 24 VDC supply, the sensor responds at up to 500 Hz, meaning it can track fast-moving targets like a cam or a passing lug on a conveyor index. The unshielded body allows flush or non-flush mounting; for unshielded sensors, derate the sensing distance if mounting in a steel environment.
IP68 ingress protection means the sensor withstands continuous immersion — suited for washdown zones in food processing, coolant splash on machining centers, or outdoor installations where rain and hose-down are routine. The plastic body resists corrosion, and the cable leads simplify wiring into a standard M12 or terminal-block interface. The LED indicator gives a quick visual check of output state during commissioning.
