Inductive Sensor for Industrial Detection

The Turck Bi2-S12-AN6X-H1141 is an NPN inductive sensor built for flush mounting in automated machinery. Its threaded M12 × 1 barrel fits standard mounting points on conveyors and assembly lines. The normally open contact switches when a metal target enters the 2 mm sensing zone. Automation engineers and maintenance technicians specify this unit for reliable position sensing.

Verify Voltage and Wiring Before Installing

Confirm your control system supplies 10 to 30 VDC and accepts a three-wire NPN output. The sensor terminates in an M12 × 1 male connector, so a matching cable or junction block is required. The PA12-GF30 housing resists oils and coolants, but check chemical compatibility for your specific plant environment. Ensure the flush mounting surface allows the rated switching distance.

Stable Output During Continuous Operation

The sensor maintains consistent switching behaviour across the full voltage range during extended production runs. The plastic housing dissipates heat without performance drift when powered continuously at 30 VDC. The sealed connector prevents signal loss from vibration or coolant ingress over long shifts. The NPN output remains clean without the bounce seen in shorter burst tests.

Questions about this item

Does the sensor ship with a mounting nut and cable or must I order them separately?

The unit is supplied as a single sensor in a box; the M12 connector is built in but a mating cable and any mounting hardware are not included.

Which sensing distance and output type match the Bi2-S12-AN6X-H1141?

This model has a 2 mm rated switching distance, flush mounting, NPN normally-open output and a 10–30 VDC supply range.

What does the 2 mm switching distance mean when the sensor is installed in a machine?

It will reliably detect a standard steel target at up to 2 mm when mounted flush in an M12 threaded hole.
