Encorder Potentiometer 20mm

EC11 Rotary Encoder Potentiometer 20mm with Push Button Switch

The EC11 Encoder Potentiometer 20mm is a compact, high-precision rotary encoder designed for applications that demand smooth, reliable signal output. Whether you’re building an Arduino project, a DIY audio amplifier, or an industrial control panel — this encoder delivers consistent 360° infinite rotation with integrated push-button functionality.

Unlike traditional potentiometers, this digital encoder supports unlimited rotational counting in both directions, making it ideal for precise volume control, menu navigation, and dimming circuits.
