Turck Bi4-M12T-AN6X Inductive Proximity Sensor

The Turck BI4-M12T-AN6X inductive proximity sensor performs non-contact detection of metallic targets with a 4 mm sensing distance (0.16 in), designed for flush-mount installation in industrial automation applications such as packaging machines, conveyors, and assembly equipment. This 3‑wire NPN normally open device operates from 10–30 VDC, switches up to 200 mA, and supports up to a 2 kHz switching frequency, with an integral 2 m (6.56 ft) cable and an M12 x 1 threaded connection in a chrome-plated brass housing. Its rugged IP67 enclosure, chrome-plated brass body, and partially threaded barrel enable reliable operation in harsh environments from −25°C to +70°C, making it suitable for position sensing and metal object detection in PLC-controlled processes. Notable features include increased sensing distance, reverse polarity protection, and short-circuit protection, with common replacements such as Turck BI4-M12T-AP6X and BI4-G12-AN6X-V1131 available for retrofit or expansion.
