What is a Multi-Turn Rotary Potentiometer?

A multi-turn rotary potentiometer is an electromechanical device that allows a variable resistance over multiple turns (often 5, 10, or 20) of a rotary knob or shaft. Unlike single-turn pots that complete their resistance range in one revolution, multi-turn potentiometers offer enhanced resolution and precision, making them ideal for fine adjustments in critical systems.

These devices are used to:

• Control position and angle in servo mechanisms
• Adjust voltage or signal gain in electronic equipment
• Provide human-machine interface inputs in aerospace, defense, and medical systems
