Product description: Hybrid potentiometer AL24
Precise hybrid potentiometer with a long lifetime
The multiturn potentiometers in the AL24 series combine the advantages of wirewound and conductive plastic technology. Thanks to the hybrid resistor technology, the series offers almost infinite resolution and a particularly low-noise signal without winding jumps. Thanks to the smooth resistor surface, the potentiometer is characterised by a particularly long service life of over 10 million revolutions.
With a compact Ø20 mm housing and low installation depth, the AL24 is ideal for applications with high precision and space restrictions. The series is available with electrical rotation angles of 1080° (3-turn), 1800° (5-turn) or 3600° (10-turn).
The AL24 can optionally be fitted with mechanical limit switches. These are activated within the electrically effective angle of rotation (360° × n) and enable direct signal feedback when defined positions are reached. The following variants are available:
CW+CCW: Limit switch for both directions of rotation
CW: Limit switch for clockwise rotation
CCW: Limit switch for anti-clockwise rotation
Options:
- Electrically effective angle of rotation: 1080° (3 turn), 1800° (5 turn) or 3600° (10 turn)
- Resistance values: 1 kOhm to 100 kOhm
- Independent linearity: ±0.25 % (optionally up to ±0.1 %)
- Shaft adaptations: Various geometries and lengths
- Rear shaft: Additional mechanical connection options
- Shaft sealing: IP65 for increased protection requirements
- Mechanical limit switches: CW+CCW, CW or CCW
- Slipping clutch: Protects against overload due to unintentional rotary movements
- Tandem version: Up to 2 potentiometers for redundant signal output
- Centre tap: Enables extended measured value output and use as a voltage divider
- Screwdriver slot: For simple manual adjustment of the shaft
