Overview
The Turck BI4-M12-AP6X-0.2-RSAT embeddable inductive sensor delivers precision object detection in applications requiring tight spatial integration. This industrial-grade proximity sensor operates across the 10-30VDC range, making it compatible with standard PLC and automation control systems. Its 4mm rated switching distance and metal-housing design provide consistent performance in metalworking, assembly automation, and material handling environments.
