Same as above. Continuous rotation -stops available. Many more models and options available .
Conductive plastic provides essentially infinite resolution and long life.
Wirewound provides more stability under temperature changes and better linearity. For protection from very moist or harsh environments use an oil filled pot. Available with either a wirewound or conductive element. We suggest using servo mount , servo mount with ball bearings or a bushing mount with ball bearings to achieve minimum radial shaft play and runout when attaching a gear or precision mechanism.
