Overview
The Turck BI4-Q06-AP6X2-0.8-PSG3M/S1174 is an inductive proximity sensor engineered for flush-mount, embeddable applications. Part of Turck’s BI4 series, this compact 6 mm rectangular sensor detects ferrous and non-ferrous metals with a 4 mm rated switching distance. The S1174 variant is optimized for reliable performance in industrial automation, control, and monitoring systems.
