Industrial proximity sensor

The Turck BI5-S18-AN6X 46561 is an inductive sensor with NPN output designed for flush mounting in M18 x 1 threaded barrels. It operates on 10 to 30 VDC with a normally open contact and a rated switching distance of 5 mm. The housing uses PA12-GF30 plastic and connects via a fixed cable.

Suited for DC automation lines

This sensor fits machines that need a flush-mounted M18 inductive probe with NPN switching on a 3-wire DC supply. It is not for applications requiring PNP logic, AC voltage, non-flush mounting or a larger sensing range than 5 mm. Buyers needing a different thread size or connector type should look elsewhere.

5 mm switching distance headroom

The 5 mm rated distance reliably detects standard ferrous targets at close range in flush installations. Headroom drops when targets are smaller than the sensing face, non-ferrous or positioned beyond 5 mm. The 10 to 30 VDC supply window gives stable operation across typical industrial DC rails.

Questions about this item

What voltage supply does the BI5-S18-AN6X 46561 require to operate?

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

Can I mount this M18 sensor flush in a metal bracket that holds older M18 devices?

Yes, the flush-mount design and M18 × 1 thread let it sit level with the bracket surface without interfering with adjacent hardware.

How do I verify the NPN output is switching at the rated 5 distance?

Apply 10…30 VDC, bring a metal target to the 5 switching distance, and confirm the load connected to the black wire turns on when the target arrives.
