Conductive plastic or wire wound element? Conductive plastic element provides essentially infinite resolution and long life.
Wire wound provides more stability under temperature changes and better linearity.
Go to Single turn conductive plastic pots . Go to Single turn carbon comp pots .
Using a gear on the pot shaft ? 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
