Turck BI5U-EM18-AN6X-H1141 inductive sensor NPN M18 electrician tool

Industrial inductive sensor for electricians

The Turck BI5U-EM18-AN6X-H1141 is a flush-mount M18 × 1 sensor with an NPN normally-open output. It operates on 10…30 VDC through a three-wire DC connection and terminates in an M12 × 1 male connector. The stainless-steel housing uses grade 1.4301 (V2A) for corrosion resistance. This unit suits maintenance and automation engineers who need reliable metal detection in harsh environments.

Sustained-load detection performance

Rated switching distance is 5 mm with factor 1 across all metals, so ferrous and non-ferrous targets trigger at the same range. High switching frequency supports rapid cycling on conveyor or packaging lines without signal degradation. The uprox®+ design maintains consistent output during continuous operation, and resistance to magnetic fields prevents false trips near welding equipment or large motors. Buyers who need analogue output or longer range should consider other models.

Environmental durability and power

Protection class IP68 seals the barrel against dust and prolonged immersion, while the extended temperature range handles cold stores and hot process zones. Current draw stays within the 10…30 VDC supply window, and the 45 g weight adds minimal mass to moving fixtures. The connector format allows quick replacement without rewiring. Installations requiring AC supply or wireless signalling are not supported by this device.
