3590 Family

Model 3590 was introduced to address standard, high-volume applications. In this regard, it has fewer optional features than the 3590. This model is one of the lowest cost precision potentiometers on the market. Yet, the 3590 family offers high performance and several standard configurations:

  • 3590-1: plastic bushing and plastic shaft
  • 3590-2: metal bushing and metal shaft; comparable in performance to Model 3540
  • 3590-3: plastic bushing and plastic shaft; sealed against humid environments and board washing
  • 3590-4: metal bushing and metal shaft; sealed against humid environments and board washing
  • 3590P: PC terminals for compatibility with board mounting
