SoftPot Linear Position Sensor – 100mm

The Linear SoftPot Ribbon Sensor – 100 mm is a thin, membrane-based position sensor designed to provide linear analog position feedback along its active length. It features a nominal 10 k? resistance across the outer terminals, while the center terminal outputs a variable voltage depending on the touch position. The sensor includes an adhesive backing for secure mounting and operates with 3–5 V systems using a series resistor configuration. Built for reliable and repeatable position sensing, it is suitable for control panels, musical interfaces, human–machine interfaces, and embedded analog input applications.
