Multiturn-Wirewound Potentiometer AL25

Versatile multiturn potentiometer for precise control tasks

With its compact Ø25 mm plastic housing and a rotary movement of up to 20 turns, the AL25 series offers a flexible solution for applications that require maximum precision and reliability. With a service life of 2 million turns and an outstanding linearity of ±0.25 % (option: ±0.10 %), this potentiometer is ideal for demanding control and regulation tasks.

A tandem version is available for applications that require redundant or galvanically isolated signals. Another option of the AL25 series are limit switches that can be activated within the electrically effective angle of rotation (360° × n). Available types:

• CW+CCW: Limit switch for both directions of rotation
• CW: Limit switch for clockwise rotation
• CCW: Limit switch for anti-clockwise rotation

Additional options such as center taps and a rear shaft extend the application possibilities of the series.

Options:

• Limit switch: Types CW, CCW or CW+CCW - Inscription type: Limit switches are activated within the electrically effective angle of rotation (360° × n)
• Tandem version: For redundant or galvanically isolated signal output
• Centre taps: Up to 5 taps of the resistor element
• Front shaft: Numerous geometries available; customisation of other geometries on request
• Rear shaft: Additional mechanical connection options
• Linearity: ±0.25 % (option: ±0.10 %)
• Resistance values: 100 Ohm to 200 kOhm
• Screwdriver slot: For simple manual adjustments
• Shaft seal: For applications with increased protection requirements (IP65)
