Technical Datasheet: TURCK BI5U-MT18-AP6X-H1141

Series: uprox®+ (Extended Range Factor 1 Sensor)

Ident-No.: 1635240

1. Product Characteristics & Application

• Sensor Type: Inductive Proximity Sensor

• Housing Design: Threaded barrel type (M18 × 1) with a robust chrome-plated or Marine-grade Brass barrel construction (MT designator).

• Sensing Range ($S_n$): 5 mm

• Mounting: Flush mountable (indicated by the flush installation graphic layout on the packaging label).

• Special Features: uprox®+ technology (Factor 1) — detects all magnetic and non-magnetic metals (steel, stainless steel, brass, aluminum, copper) at the exact same distance of 5 mm without any reduction factor. It features exceptional immunity to strong magnetic fields (weld-field immune), making it ideal for harsh automated body shops, heavy welding lines, and automotive stamping machinery.
