Turck NI4-M12-VN6X Inductive Proximity Sensor

The TURCK NI4-M12-VN6X Inductive Proximity Sensor is a compact, non-contact metal-detection sensor designed for industrial machine position sensing. It features a 4 mm sensing distance, M12×1 threaded barrel, chrome-plated brass housing, and a PA12-GF30 active face for easy mounting on conveyors, packaging machines, and assembly lines. Operating on 10–30 VDC with a 4-wire DC configuration, it delivers up to 200 mA and uses complementary NPN outputs (NO/NC) with short-circuit and reverse polarity protection for reliable PLC integration. Rated IP67 and capable of -25°C to +70°C operation at a 2 kHz switching frequency, this sensor supports non-contact metal object detection, end-of-travel sensing, and part presence verification in automation setups; common replacements include NI4-M12-VN6X-H1141, BI4-M12-VN6X, and NI4-M12-AN6X.
