Turck NI12U-MT18H-AP6X2-H1141 S1589 Proximity Switch

The TURCK NI12U-MT18H-AP6X2-H1141 S1589 Proximity Switch is a non-contact inductive sensor that uses UPROX Factor 1 sensing to reliably detect metallic targets at a 12 mm nominal distance, with a PNP normally open output for straightforward integration with standard industrial controllers. Built for harsh welding and magnetic-field environments, it features a PTFE-coated brass housing in an M18 × 1 partially threaded barrel with Weld Guard coating, IP68 protection, an operating range of -30°C to +85°C, and a 10–30 VDC supply that draws up to 200 mA, plus a 4-pin M12 male connector and a 1 kHz switching frequency for fast, repeatable sensing; it also includes integrated protection against pre-damping and magnetic-field resistance. The device is commonly used in robotic welding cells, automotive body assembly lines, transfer and conveyor systems, and other automated machinery for metal object detection and precise machine positioning, and is part of TURCK’s replacement family with compatible options such as Bi4-M12-AP6X-H1141 and NI15U-MT18M-AP6X2-H1141/S1589.
