Technical Datasheet: TURCK BI3U-EM08-AP6X-V1131

Series: uprox® 3 (Generation 3 Factor 1 Sensor)

Ident-No.: 4602413

1. Product Characteristics & Application

• Sensor Type: Inductive Proximity Sensor

• Housing Design: Threaded barrel type (M8 × 1)

• Sensing Range (Sn): 3 mm (Extended sensing range for M8 size)

• Mounting: Flush mountable

• Special Features: uprox® 3 technology (Factor 1) — detects all metals (steel, stainless steel, brass, aluminum, copper) at the exact same extended distance of 3 mm without any reduction factor. It features a high-grade stainless steel housing (EM08 series) and offers ultimate immunity to strong DC and AC magnetic fields (weld-field immune), making it perfect for high-density automotive welding lines and tight machine gaps.
