Turck BI2-Q5.5-APX6X Inductive Proximity Sensor

The Turck BI2-Q5.5-AP6X is a compact, flush-mount inductive proximity sensor for non-contact detection of metallic targets in industrial automation. It features a 2 mm sensing distance and a 3‑wire PNP normally open output, operates from 10–30 VDC, and tolerates up to 150 mA of switching current, with a switching frequency up to 2 kHz. An integral cable suits quick installation, and the device is housed in a rectangular Q5.5 package made of glass-filled polypropylene (PP-GF20), measuring 28 × 8 × 5.5 mm and rated IP67 for robust use in packaging machines, conveyors, and assembly equipment. Flush-mount design enables surface installation in tight spaces, and it is suitable for position sensing and metal object detection across industrial automation environments from −25°C to +70°C. Common applications include packaging lines, material handling systems, conveyors, and robotic work cells that require reliable, non-contact metal detection for PLC-controlled processes. Common replacements include Turck BI2-Q8SE-AP6X, BI2-Q10S-AP6X, and BI2-M12-AP6X-H1141.
