Turck NI12UMT18HAP6X2H114 Inductive Proximity Sensor

Turck NI12UMT18HAP6X2H114 is a 12 mm nominal inductive proximity sensor from the NI12U uprox series for non-contact detection of metallic targets in harsh industrial environments. It uses Turck’s uprox Factor 1 technology to provide identical sensing distances across metals such as steel, aluminum, brass, and stainless steel, making it well suited for metal object detection and machine positioning in welding fixtures, conveyors, automotive production lines, and automated equipment. The device features an M18 × 1 threaded barrel (housing size M18) and a 3‑wire DC output configured as PNP Normally Open (NO) with a supply of 10–30 VDC and a maximum load current of 200 mA; switching frequency up to 1 kHz supports fast, reliable sensing. Connection is via an M12 connector (H114 style), while housing options include chrome-plated brass or PTFE‑coated brass depending on version; it carries IP68 protection and operates from −30°C to +85°C. An LED indicator shows sensing status, and special features include resistance to magnetic weld fields and general weld-field immunity, enabling dependable performance in metalworking and assembly lines.
