Industrial M12 inductive sensor

The Turck BI2-M12-AD4X 44050 is a flush-mountable inductive proximity sensor built for industrial automation and machine monitoring. Its M12 × 1 threaded brass barrel installs directly into standard mounting points on conveyors, presses or robotic cells. Electricians and maintenance technicians use it to detect metal targets without physical contact. The chrome-plated housing resists coolant, oil and mechanical wear in harsh production environments.

Two-wire DC cable output

The sensor operates on a 10…65 VDC supply and provides a normally-open 2-wire output that connects in series with the load. A pre-wired cable tail eliminates the need for a separate connector and reduces potential failure points at the junction. This wiring scheme simplifies installation in tight cable trays and lowers component count in control cabinets. The three-year parts coverage reflects the rugged construction intended for continuous duty cycles.

Two-millimetre switching distance

The rated switching distance of 2 mm defines the maximum reliable detection range for ferrous targets. Applications requiring a larger sensing gap or non-flush mounting will need a different sensor variant. The fixed cable length and 2-wire topology also limit flexibility where plug-in connectors or PNP/NPN selectable outputs are specified. Verify the 2 mm range suits the mechanical tolerances of the intended mounting position before ordering.

Questions about this item

Will the M12 × 1 threaded barrel or the chrome-plated brass housing need replacement under normal industrial use?

The sensor has a 3-year parts warranty covering the M12 × 1 barrel and chrome-plated brass housing; only the 2-wire cable may require inspection if flexed repeatedly.

What limits continuous operation — the 10…65 VDC supply range or the 2 mm switching distance?

The 2 mm rated switching distance is the fixed mechanical limit; the 10…65 VDC range simply defines the voltage window for reliable NO contact switching.

How much heat does the 102 g sensor generate when powered at 65 VDC all day?

As a 2-wire inductive proximity switch it draws only the load current through the NO contact, so self-heating stays negligible during continuous 65 VDC operation.
