Wirewound potentiometer F25
Wirewound Potentiometer F25: Precision and Long Life
The wirewound potentiometer F25 is designed for demanding industrial applications requiring precise adjustment and long-term stability. Its extremely low torque, starting as low as 0.003 Ncm, enables highly sensitive control, making it an excellent choice for use in measuring instruments with pointer functionality.
Main Features and Advantages
- Exceptionally low torque (as low as 0.003 Ncm) for smooth, sensitive adjustment
- High-quality materials: aluminium housing, stainless steel shaft, precious metal slider and winding ensure durability and corrosion resistance
- Multiple mounting options: clamping claws, mounting foot, synchro flange, and screw connection (M2)
- Electrical and mechanical angle up to 290° or up to 358°/360°, supporting a variety of application needs
- Long service life, rated for up to 50 million grinder travel cycles at 360°
- Protection class IP60 for use in controlled industrial environments
- Available with different resistances (1, 2, 5 kOhm ±3%) and linearity of ±0.3%
- Custom options available: reduced torque (down to 0.001 Ncm), center tap, resistance tolerances ±1%, or metal case for oil-filled instruments
