Turck BI1-EH04-AP6X Inductive Proximity Sensor

The Turck BI1-EH04-AP6X is a compact, IP67-inductive proximity sensor with a Ø4 mm smooth barrel and a 1 mm sensing distance, designed for reliable non-contact metal detection in tight installations. It runs on 10–30 VDC and offers a 3‑wire PNP normally-open output up to 100 mA, with a 2 m PUR cable and flush (embeddable) mounting for discreet integration, and it switches at up to 3 kHz while displaying a yellow status LED. Its stainless steel (AISI 303) housing and PA6.6 active face resist industrial environments, and the unit includes short-circuit and reverse polarity protection across a -25°C to +70°C operating range, making it suitable for automatic lines that require dependable sensing. Common applications include conveyors, packaging equipment, assembly machines, robotic work cells, automated manufacturing systems, and material handling where precise metal object detection supports process control and production efficiency. Common replacements include Turck BI1-EH04-AN6X, BI1-EH04-AP6X-V1331, and BI1-EH04-AP6X-7M.
