M12 NAMUR inductive sensor

The Turck BI2-P12SK-Y1X 40310 is a flush-mount inductive proximity sensor with a threaded M12 × 1 barrel made from PA12-GF30 plastic. It operates on a nominal 8.2 VDC supply using a DC 2-wire NAMUR output compliant with DIN EN 60947-5-6. Connections are made via an integrated terminal chamber and the unit weighs 57 g.

Suited for hazardous-area position sensing

This sensor suits engineers specifying NAMUR-compliant devices for intrinsically safe circuits in process automation or industrial safety systems. It is not intended for applications requiring standard PNP or NPN switching outputs, higher switching distances, or metal-housing durability in heavy mechanical abuse.

2 mm switching distance with terminal wiring

The rated switching distance of 2 mm provides reliable detection of ferrous targets at close range when mounted flush. Headroom is limited to this short range; the sensor cannot detect objects further away or through non-metallic barriers, and the terminal chamber requires wired installation rather than a quick-disconnect plug.

Highlights

  • M12 × 1 threaded barrel for secure flush mounting
  • NAMUR output per DIN EN 60947-5-6 for intrinsic safety
  • 2 mm rated switching distance detects targets reliably
  • PA12-GF30 housing resists chemicals and impact
  • Terminal chamber simplifies field wiring

Questions about this item

Does the M12 × 1 threaded barrel fit standard M12 mounting hardware?

Yes, the sensor uses an M12 × 1 threaded barrel that matches standard M12 mounting hardware for flush installation.

Can the sensor operate with an 8.2 VDC NAMUR power supply used by older control systems?

Yes, it is a DC 2-wire NAMUR device with a nominal 8.2 VDC supply, compatible with legacy NAMUR input modules.

How can I verify the sensor is switching at the rated 2 mm distance after installation?

Bring a standard steel target to 2 mm from the sensing face; the NAMUR current change at the terminal chamber confirms correct switching.
