Overview
The Turck BI2-S12-AP7X/S100 is a 12mm embeddable inductive proximity sensor designed for factory automation and process control applications. This potted-in sensor provides robust non-contact object detection in demanding industrial environments, including high-temperature and washdown conditions. The compact barrel design enables flush or semi-flush mounting, making it ideal for confined spaces and integration into automated machinery.
Key Features
