Turck Ni12U-S18-AN6X Inductive Proximity Sensor

The TURCK NI12U-S18-AN6X is a compact M18-equivalent inductive proximity sensor that detects metal objects without contact using UPROX Factor 1 technology, delivering a 12 mm nominal sensing distance across steel, aluminum, brass, and stainless targets, with resistance to magnetic fields. It provides an NPN normally-open output, operates on 10–30 VDC with a maximum load current of 200 mA, and switches at up to 1 kHz, making it suitable for automated lines, conveyors, packaging equipment, assembly cells, robotic workstations, and other metal-detection applications. The device features a thermoplastic smooth housing, non-flush mounting, and an IP67 rating for harsh industrial environments, with an operating temperature range of -30°C to +85°C, and is available in cable or connector variants. Identification Number 1645520; common replacements include TURCK NI12U-M18-AN6X-H1141, TURCK BI10U-S18-AN6X, and IFM Electronic IFS240.
