Turck BI1-HS540-AN6X Inductive Proximity Sensor

The Turck BI1-HS540-AN6X inductive proximity sensor delivers reliable non-contact metal object detection in automated systems, packaged in a compact Ø4 mm smooth-barrel housing with a 30 mm length and a lateral active sensing face for flush, embeddable mounting. It senses metal targets at up to 1 mm with a 3‑wire, NPN normally open output and operates on 10–30 VDC, up to 150 mA of load current, with a switching frequency of 3 kHz. The sensor comes with a 2 m PUR cable and uses a stainless steel (1.4427 SO) housing with a PA12-GF30 plastic active face, rated IP67 for harsh environments and an operating temperature range of -25°C to +70°C. It includes short-circuit and reverse polarity protection and a Yellow LED indicator that shows switching status. Common replacements include Turck BI1-HS540-AP6X, BI1-HS540-AN6X-0.2-PSG3, and BI1-EH04-AN6X, making it suitable for conveyor systems, packaging equipment, assembly machines, robotic work cells, and other automated manufacturing setups where reliable metal detection and process control are essential.
