Industrial Inductive Sensor M18 5mm NAMUR

The Turck BI5-G18-Y1X is a flush-mount inductive proximity switch with an M18 × 1 threaded barrel. It operates on an 8.2 VDC two-wire NAMUR output compliant with DIN EN 60947-5-6. The chrome-plated brass housing provides durability in industrial environments. It carries ATEX approvals for gas and dust zones plus SIL2 and PLc functional safety ratings.

Suited for Hazardous-Area Position Sensing

This sensor fits machine builders and maintenance engineers who need a certified NAMUR device for explosive atmospheres. The flush mounting style allows installation level with surrounding metal. Buyers requiring a non-NAMUR output such as PNP or NPN switching should select a different model. Applications needing a longer sensing range than the rated 5 mm must consider alternative constructions.

Rated 5 mm Switching Distance with Safety Headroom

The 5 mm rated switching distance reliably detects ferrous targets in typical automation tasks. Stainless steel or non-ferrous materials reduce the effective range, so verify material compatibility during design. The NAMUR output provides intrinsic safety when paired with approved isolating barriers. The 125 g weight and cable connection simplify integration into existing conduit runs.

Questions about this item

What supply voltage must the NAMUR interface provide for the BI5-G18-Y1X sensor?

The sensor operates on a nominal 8.2 VDC supply through its DC 2-wire NAMUR output, compliant with DIN EN 60947-5-6.

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

Yes, the housing is chrome-plated brass and rated for flush mounting, so it installs directly into a standard M18 × 1 threaded hole.

How do I verify the sensor is operating correctly after installation?

Monitor the NAMUR current signal; it will drop below 1.2 mA when metal enters the 5 mm switching zone and rise above 2.1 mA when clear, confirming proper function.
