Turck NI4-M12-AD4X-H1141 Inductive Proximity Sensor

The TURCK NI4-M12-AD4X-H1141 Inductive Proximity Sensor is a compact 2‑wire DC, normally open device engineered for non‑contact metal detection and precise machine position sensing in industrial automation. With a 4 mm sensing distance, M12 × 1 threaded barrel, chrome‑plated brass housing, and IP67 rating, it operates from 10–65 VDC and can source up to 200 mA, switching at up to 1 kHz. LED status indication is built in, and the sensor features short-circuit protection and wear‑free operation for reliable sensing in harsh environments. It is commonly used in conveyors, material handling, packaging machines, automotive assembly lines, and other manufacturing processes requiring end‑of‑travel sensing, part presence verification, and machine sequencing, with a 2‑wire DC design that integrates into relay logic circuits and legacy controls. Common replacements include TURCK NI4-M12-AN6X-H1141, BI4-M12-AP6X-H1141, and BI4-M12-VN6X-H1141.
