AL24 Multiturn Hybrid Potentiometer
AL24 Series Multiturn Hybrid Potentiometer

-  5 and 10 Turn Models

-  Up to 10 Million Turns Life

-  High Precision
  

The AL24 series of multi-turn wire-wound potentiometers set the standard for high precision, industrial quality in a small (20mm) diameter package. True Hybrid technology combines the infinite resolution and long life of conductive plastic with a traditional wire-wound element for superior performance.
