Turck Bi4-M12-VN6X-H1141 Inductive Proximity Sensor

The Turck BI4-M12-VN6X-H1141 inductive proximity sensor delivers non-contact metal detection for industrial automation, with a 4 mm sensing distance and a compact M12 x 1 threaded housing. It uses 4-Wire NPN Complementary outputs (NO + NC) for flexible PLC control and machine interlocks, operated from 10–30 VDC with a maximum switching current of 200 mA and a switching frequency up to 2 kHz. The sensor mounts in a threaded chrome-plated brass housing with an M12 x 1 thread, featuring a PA12-GF30 active face and flush-mount capability for tight installations. It carries an IP67 protection rating and is suitable for -25°C to +70°C industrial environments, making it well-suited for packaging machines, conveyors, assembly equipment, robotic cells, and general material handling. Built-in reverse polarity protection, short-circuit protection, and a status LED indicator help verify operation and simplify diagnostics. For replacement or expansion, Turck lists common alternatives such as BI4-M12-AN6X-H1141, BI4-M12-AP6X-H1141, and BI4U-M12-VN6X-H1141.
