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.
