Turck Ni2U-M18-AN6X Inductive Proximity Sensor

Turck NI2U-M18-AN6X is a threaded M18 inductive proximity sensor (Uprox Factor 1) designed for non-contact metal object detection and machine position sensing in harsh industrial environments. It is commonly installed on conveyor systems, packaging machinery, assembly equipment, material handling networks, and automated production lines, with additional use in robotic work cells, sorting equipment, and automotive assembly lines where precise metal target detection and sequencing are required. The sensor provides a NPN normally open (NO) output with 10-30 VDC operation and a 200 mA rated output current, housed in chrome-plated brass with an integral cable (3-wire DC) in a compact M18 x 1 form factor. It carries IP67/IP68 protection and operates from -30°C to +85°C, making it suitable for dirty or wet industrial settings. Notable features include Factor 1 sensing for all metals, magnetic field immunity, short-circuit protection, and reverse polarity protection. Common replacements include TURCK NI4U-M18-AN6X, NI8U-M18-AN6X, and NI12U-M18-AN6X-H1141.
