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 important.

The precision potentiometers of the AL17/19 series are manufactured under the highest quality requirements. In particular, the made of the wirewound resistance element, which is manufactured with know-how of great mechanical precision, stands out among the high-quality components. As a result, the AL17/19 series has superior technical characteristics and enjoys great popularity due to its cost efficiency and numerous customization possibilities.

The AL17 / AL19 multiturn potentiometers (standard shaft: Ø6.35 / Ø6.00 mm) are available as 3-, 5- or 10-turn versions. The screwdriver slot already positioned on the shaft makes a zero-point adjustment convenient. Two connection variants are available for electrical coupling:

  • 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.  

For optimal integration into the application, the following options are available: 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":
Multiturn potentiometers have so-called end stops so that the wiper does not "slide" behind the edges of the resistor track. The option "integrated slipping clutch" protects the potentiometer from overstressing / mechanical damage of the end stops. We recommend this option for applications in which overrunning of the resistance track cannot be generally avoided.

The potentiometers of the AL17/19 series are precision potentiometers. In comparison to commercially available low-cost potentiometers, they have a significantly higher lifespan, reliability and quality. As a result, they offer precise position measurements with a significantly longer operating time than low-cost potentiometers, which consequently results in lower maintenance costs or reduced downtime of applications.  

  • Economical and precise multi-turn sensor
