Product description: Multiturn Wirewound Potentiometer AL17/19

The AL17/19 potentiometers in Ø22 mm housing are suitable for applications where a precise and economical multiturn potentiometer is required.

The precision potentiometers of the AL17/19 series are manufactured under the highest quality requirements. In particular, the series is distinguished by its high quality components, which are made from wirewound resistive elements and manufactured with high-precision mechanical know-how. As a result, the AL17/19 series has superior technical characteristics and is very popular due to its cost efficiency and numerous customization options.

The AL17/AL19 multiturn potentiometers (standard shaft: Ø6.35 / Ø6.00 mm) are available in 3, 5 or 10-turn versions. The screwdriver slot on the shaft allows easy zero adjustment. Two connection options are available for electrical connection:

  • version with radially gold-plated connection pins - suitable for blade terminals (2.8 mm) according to DIN 46247 part 3
  • version with completely factory-assembled connector - simplifies assembly and serves to prevent short-circuits.  

The following options are available for optimum integration into the application: linearity, resistance value and tolerances, shaft geometry (front or rear) as well as tandem/multi-gang alignment or special sealing (completely enclosed IP67).

ALR17/19 with "integrated slipping clutch":
Multi-turn potentiometers have so-called end stops to prevent the wiper from "slipping" beyond the edges of the resistance track. The option "integrated slipping clutch" protects the potentiometer from overstressing / mechanical damage to the end stops. This option is recommended for applications where overrunning of the resistance track is unavoidable.

The AL17/19 series are precision potentiometers. Compared to commercially available low cost potentiometers, they have a much higher life span, reliability and quality. As a result, they provide accurate position measurement with a much longer operating life than low-cost potentiometers. This results in lower maintenance costs and reduced application downtime.

  • Economical and precise multi-turn sensor
  • Simplified mounting due to connector version
  • Optionally with an integrated slipping clutch
  • Many other options are available


  • Front shaft sealing
  • Connector version
  • Improved linearity
  • Improved resistance tolerance
  • Rear shaft and shaft geometry
  • Front shaft modification
  • Center tap
  • Tandem version
  • Housing protection IP67

Many adaptations are available on request: Tandem or multi-ganged potentiometers, sealed housings, special electrical and mechanical rotation angles, and special resistance and linearity tolerances. We can also mount gears, attach cable assemblies with or without connectors, and much more.
