Turck BI3U-M12-AP6X-H1141 Inductive Proximity Sensor

The Turck BI3U-M12-AP6X-H1141 is a compact, M12-connected inductive proximity sensor designed for non-contact metal detection in industrial automation. Built with Turck uprox technology, it delivers equal sensing distance across all metals while resisting magnetic fields and harsh environments. It features a 3 mm (0.12 in) sensing distance, a 3-Wire PNP normally open output, and operates on 10–30 VDC with a maximum switching current of 200 mA and a 2 kHz switching frequency. The flush-mount, threaded-barrel housing is chrome-plated brass with an M12 x 1 connector, IP67 protection, and built-in reverse polarity and short-circuit protection, plus a yellow LED status indicator. Typical applications include packaging machines, conveyors, and assembly equipment for PLC-controlled position sensing and non-contact object detection in industrial settings.
