Product identity

The Turck Bi5-G18-AN6X 4641500 is an inductive proximity sensor with a threaded M18 x 1 barrel designed for flush mounting in metal environments. It operates on 10…30 VDC supply voltage and provides a normally open NPN output through a cable connection for direct integration into DC control circuits.

Suitability

This sensor suits automation engineers and maintenance technicians who need a flush-mountable metal detector with a 5 mm rated switching distance and NPN logic for PLC input compatibility. Buyers who require a PNP output type, a non-flush mounting style, or a connector-based electrical interface should look at alternative models.

Build integration

The chrome-plated brass housing withstands industrial conditions while the 3-wire DC cable simplifies wiring without additional connectors. Its flush mounting design allows the sensor face to sit level with surrounding metalwork, saving space in compact machine frames. The 10…30 VDC range matches common control voltage standards.

Questions about this item

What power supply voltage range does the Bi5-G18-AN6X sensor require?

The sensor operates on a DC supply from 10 to 30 VDC, so any power source within that range will power it correctly.

Can the M18 × 1 threaded barrel be mounted flush in an existing M18 hole?

Yes, the housing is designed for flush mounting with an M18 × 1 thread, matching standard M18 clearance holes.

How do I verify the NPN output switches when a target enters the 5 mm sensing zone?

Connect a multimeter or PLC input to the black output wire; the signal should pull low when metal reaches the 5 mm rated switching distance.
