In complex mechanical systems, it is often very difficult to accurately measure the movement of a single part, especially if the linear alignment isn't guaranteed to be perfect. The draw-wire encoder is a versatile solution to this very problem. When the wire is pulled out, the encoder produces a quadrature signal to describe the change in distance.
