Overview
The Turck BI2-CRS260-ADZ30X3-B3131/S34 is an inductive proximity sensor engineered for reliable position sensing in industrial automation and motion control applications. This 26 mm probe-length sensor offers a compact cylindrical body with embeddable installation, making it suitable for direct mounting on pneumatic cylinders and linear actuators. The sensor operates on 2-wire AC/DC technology, eliminating the need for complex wiring in tight spaces.
