Draw wire encoders (string encoders / string potentiometers) use a reel of spring-loaded cable connected to a rotary encoder or potentiometer to provide highly accurate length measurements as the cable is extended. Quadrature and analog outputs are available on models with lengths from 2 to 10 meters.

Compact and accurate linear measuring using a retractable stainless-steel draw wire. Draw wire encodes offer a flexible and relatively simple way to measure linear position that can be used in environments where traditional linear encoders are difficult to install. They can accurately measure linear displacement over long distances and can be mounted in various orientations.
They are a good solution when the operational space is constricted, or the environmental conditions are severe. The body of the encoder can be mounted in a safe place, easily accessible, and adequately protected, while the measuring wire requires minimum space and can be subjected to harsher conditions. They can also replace traditional encoders in some cases. Typical applications include linear measuring, vertical lift measurement, cylinder stroke measurement, or any application where accurate, inexpensive, and easy to install measurement of a linear distance is required.
