Turck BI20U-CA40-AP6X2-H1141 Inductive Proximity Sensor

The Turck BI20U-CA40-AP6X2-H1141 is a long-range, non-contact inductive proximity sensor for industrial metal detection and position sensing, featuring a 20 mm sensing distance and uprox technology for reliable metal detection across varying target materials. It provides a 3‑wire PNP normally open output, operates on 10–30 VDC, and can switch up to 200 mA at a maximum 250 Hz, with an M12 x 1 male connector and a rectangular CA40 housing made from PBT-GF30-V0 plastic rated IP68 for flush surface mounting in harsh environments. Key features include Factor 1 sensing for all metals, magnetic field resistance, extended sensing distance, and a high switching frequency, enabling dependable detection of steel, aluminum, brass, and stainless steel in PLC-controlled processes. Typical applications encompass conveyors, packaging machines, material handling equipment, pallet handling systems, and automated production lines requiring long-range, non-contact object detection and position sensing. Common replacements include Turck BI20U-QV40-AP6X2-H1141, BI15U-CK40-AP6X2-H1141, and NI20U-CA40-AP6X2-H1141.
