M18 inductive sensor with PNP output

The Turck BI8-EM18-AP6X-H1141/S1589 is a flush-mount inductive sensor built for industrial automation and machine monitoring. Its stainless-steel V2A housing resists coolants and weld spatter, making it suitable for production lines and welding cells. Electricians and maintenance engineers install it where reliable metal detection is required. The 10 to 30 VDC supply range fits standard control cabinets.

8 mm switching distance and M12 connector

Rated switching distance reaches 8 mm on mild steel, giving enough headroom for target approach variation and sensor wear. The three-wire DC circuit with normally-open PNP output integrates directly with PLC input modules. An M12 × 1 male connector provides a secure, vibration-resistant electrical link. Operation ceases outside the 10 to 30 VDC window, so voltage drops on long cable runs must be checked.

weldguard coating and connector simplify

The weldguard® coating on the sensing face reduces weld-spatter adhesion, cutting cleaning downtime in robotic welding stations. A single M12 connector replaces hard-wired leads, speeding sensor swaps during planned maintenance. The sensor ships as a single unit in a box without mounting nuts or cables, so installers must supply compatible M12 cordsets and M18 mounting hardware.

Questions about this item

Will the M18 × 1 threaded barrel fit the existing mounting holes on my older machine frame?

The sensor uses an M18 × 1 thread, so it matches any M18 clearance hole; the 8 mm rated switching distance works with the same target spacing you already use.

How can I confirm the PNP output is switching correctly after I wire the M12 × 1 connector?

With 10–30 VDC applied, the NO contact closes when metal enters the 8 mm sensing zone; measure the load voltage — it should rise to supply level when the target is present.

Does the box include the M12 mating cable or must I order it separately?

Only the sensor (order number 4615099) is in the box; the M12 × 1 male connector is on the sensor itself, so a compatible female cable assembly must be purchased separately.
