The HH21 potentiometers in 20 mm housing are suitable for applications where a durable and very high-resolution multiturn potentiometer with servo flange is required.

The high-resolution precision potentiometers of the HH21 series have a wire-wound resistor element, which is finished with a conductive plastic layer. Thus the so-called winding jumps are omitted and the resolution is almost infinite. Due to the smooth surface of the resistance element, the hybrid potentiometer has a significantly longer life span.

  • Very high-resolution and long-lasting due to hybrid technology
  • Very clean signal - no winding jumps thanks to hybrid technology
  • 2 x ball bearings


  • 3-10 turn
  • Improved linearity
  • Improved resistance tolerance
  • Front shaft adaptation
  • Rear shaft adaption
  • Center tap
  • Tandem potentiometer

We offer many adaptations on request:
Multi ganged potentiometers, limit switch adaptor CW, CCW, special electrical and mechanical angles of rotation, and special resistance and linearity tolerances. Furthermore we can mount gear wheels or attach cable assemblies with or without connectors and much more.
