Industrial proximity sensor for machine builders

The Turck BI5-M18-AD4X-H1141 is a flush-mount inductive sensor with a threaded M18 × 1 brass barrel. It detects metal targets at a rated switching distance of 5 mm and provides a normally-open output through a 2-wire DC circuit. An M12 × 1 male connector allows quick integration into existing control wiring.

Stable switching across the full voltage range

The sensor operates reliably from 10 VDC up to 65 VDC without derating its sensing distance. Chrome-plated CuZn housing resists coolant splash and mechanical abrasion on the production line. The 2-wire design keeps voltage drop low even during continuous cycling at high frequency.

Low thermal load and silent solid-state operation

With no moving contacts the device generates negligible heat and emits no acoustic noise during normal use. Current draw stays minimal because the output stage only conducts when the target is present. The compact 50 g metal body dissipates what little power is produced directly into the mounting bracket.
