Rotary Potentiometer Types & Specifications
- Precision rotary potentiometers — low tolerance drift, high linearity for industrial position feedback and test equipment.
- Long-life rotary potentiometers — reinforced wiper and track materials rated for millions of rotations in HVAC, marine and automotive panels.
- Angle sensors — rotary potentiometer-based absolute angle measurement with custom output curves for valve, throttle and robotics applications.
- Audio taper (log) rotary potentiometers — A-curve for volume and tone controls in professional audio equipment.
- Multi-gang and switch combinations — stacked decks and integrated rotary switches to save panel space.
