Turck BI5-M18-VN4X Inductive Proximity Sensor

The Turck BI5-M18-VN4X is an inductive proximity sensor designed for non-contact detection of metallic targets in industrial automation. It offers a 5 mm sensing distance with a 4-wire NPN complementary output (NO + NC), enabling both normally open and normally closed signaling for PLC-controlled processes. Operable on 10-65 VDC, it draws up to 200 mA and switches at up to 500 Hz. This sensor uses an integral 2 m cable and features a chrome-plated brass, M18 x 1 full-threaded barrel (50 mm long) with flush-mount capability and an IP67 housing, suitable for rugged environments from -25°C to +70°C. Commonly installed in packaging machines, conveyors, assembly equipment, machine tools, and automated production lines where metal object detection is required, it supports replacement, retrofit, expansion, and automation system repairs. Special features include reverse polarity protection, short-circuit protection, and LED switching indication, making it a reliable choice for position sensing and object detection in industrial automation. Common replacements include Turck BI5-M18-AN6X, BI5-M18-AP6X, and BI5U-M18-VN4X-H1141.
