M18 Inductive Sensor for Metal Detection

The Turck Bi5U-M18-RP6X-H1141 is a flush-mount inductive sensor with a threaded M18 × 1 brass barrel. It detects all metals at the same rated switching distance of 5 mm thanks to Factor 1 technology. The PNP normally-closed output operates on 10…30 VDC and connects via an M12 × 1 male connector. IP68 sealing and magnetic-field resistance suit harsh industrial environments.

Upgrading from Non-Factor-1 or Lower-IP Sensors

Sensors without Factor 1 require different mounting gaps for ferrous and non-ferrous targets, complicating installation. Units rated below IP68 cannot withstand permanent immersion or high-pressure washdown. The extended temperature range and high switching frequency here replace older devices that drift with heat or miss fast-moving parts. The jump is worth it when a single sensor must handle mixed metals, wet conditions and rapid cycling.

Suits Automation Engineers Needing One Sensor

This model fits machines where stainless steel, aluminium and brass pass the same detection point. Builders who need a normally-open output or an NPN signal should look elsewhere. Applications requiring longer range than 5 mm or a different barrel diameter will need another housing style. The 46 g weight and chrome-plated brass body meet standard M18 mounting patterns without adapter plates.
