Turck Bi15-Q20-LiU-H1141 Inductive Proximity Sensor

The Turck BI15-Q20-LIU-H1141 Inductive Proximity Sensor delivers continuous position measurement and analog distance sensing in a compact Q20 housing for confined installations. With 4-Wire DC output, it provides a proportional 0-10 VDC voltage or 0-20 mA current signal, powered from 15-30 VDC, and a 4-11 mm measuring range with a 110 Hz sensing frequency, ideal for conveyor positioning, lift tables, material handling, and automated machinery requiring analog feedback. The sensor’s flush-mount rectangular body measures 68 x 40 x 20 mm, built from PBT-GF30-V0 reinforced plastic, and features a top-sensing active face, IP67 protection, operating from -25°C to +70°C, and M12 x 1 male connector (H1141) with short-circuit and reverse polarity protection. It also offers repeatability ≤1% of the measuring range and linearity deviation ≤3%, making it suitable for actuator feedback and continuous process control in PLC-based analog automation. Common replacements include Turck BI15-CK40-LIU-H1141, Turck BI15-M30E-LIU-H1141, and Turck BI8-M18E-LIU-H1141.
