Inductive sensor for industrial detection

The Turck Bi2-EG08K-AP6X is a PNP inductive proximity switch built for flush mounting in M8 × 1 threaded barrels. It suits automation engineers and electricians who need reliable metal detection on conveyors, machine tools or assembly lines. Stainless steel housing grade 1.4427 SO resists coolant, oils and mechanical wear in harsh production environments. The 3-wire DC design simplifies wiring into PLC input modules.

Rated switching distance of 2 mm

The single specification that decides fit is the 2 mm rated switching distance at DC 10…30 VDC. This defines the maximum reliable detection range for ferrous targets when the sensor is mounted flush in metal. A larger gap or non-ferrous material will reduce the effective range, so verify the target size and material before specifying. The NO contact output switches high when metal enters the sensing zone.

Low thermal load from 10–30 VDC supply

Operating from a 10 to 30 VDC rail, the sensor draws only the current required by the connected PLC input, typically a few milliamps. No active cooling is needed and the stainless steel barrel dissipates the minimal heat generated during switching. Acoustic noise is absent because the unit has no moving parts or fan. The 57 g weight adds negligible load to mounting brackets or cable trays.

Questions about this item

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

It means the sensor will reliably detect a standard metal target up to 2 mm away when mounted flush in a threaded M8 × 1 hole.

How does the DC 3-wire 10…30 VDC PNP output limit what controllers I can connect?

The sensor only works with DC supplies between 10 V and 30 V and requires a PNP-compatible input; it cannot be used with AC voltage or NPN-only modules.

What clearance and thread do I need to mount the M8 × 1 stainless-steel barrel?

You need an M8 × 1 threaded hole and enough space for the 57 g stainless-steel body to sit flush with the mounting surface.
