Turck BI5-M18-VN4X Inductive Proximity Sensor

The Turck BI5-M18-VN4X inductive proximity sensor provides reliable non-contact metal target detection with a 5 mm sensing distance for industrial automation. It is commonly installed on conveyors, packaging equipment, assembly machinery, machine tools, and automated production lines where normally open and normally closed outputs are used for PLC control, interlocks, and status monitoring. This 4‑wire NPN complementary output (NO+NC) device operates from 10–65 VDC and switches up to 200 mA at a 500 Hz rate. The unit offers an integral cable or connector version depending on configuration, and its M18 threaded barrel, chrome-plated brass housing, and M18 x 1 thread support flush mounting in demanding environments. With IP67 protection and an operating temperature range of -25°C to +70°C, it is designed for rugged industrial use. Key features include reverse polarity protection, short-circuit protection, and LED switching indication to confirm detection. The BI5-M18-VN4X is a common Turck replacement option for packaging machines, conveyors, robotic assembly cells, and other manufacturing equipment requiring accurate, contactless metal object detection. Compatible replacements include BI5-M18-AN6X, BI5-M18-AP6X, and BI5U-M18-VN4X-H1141.
