HEM12 Series

Heavy duty, precision, linear potentiometer (transducer). Welded stainless steel tubular housing (12mm diameter) for an IP67 environmental rating. In-cylinder (hydraulic) applications of 250 bar (400 bar peak). A threaded donut (sliding) cursor provides a magnetic coupling to the internal sliding wiper. Essentially infinite resolution. 100 million cycle life. Measuring lengths (stroke lengths) of 50mm (max) up to 1000mm (max).
