11.8mm-diameter EC11 5-pin Rotary Encoder

Precision Rotary Encoder for Smooth Control

The EC11 5-pin rotary encoder delivers precise rotary input for your electronics. With a 360-degree rotating shaft and an integrated push-button switch, it enhances user interaction and control. Its compact 11.8mm design fits neatly into space-constrained layouts, supporting efficient panel integration in automotive, industrial, and home devices.

Built for Versatility and Durability

We construct the encoder using metal and high-grade plastic for reliable operation. The tactile feel offers smooth feedback during rotation and pressing. It supports both incremental rotation and button input, increasing interface flexibility. Engineers can confidently deploy it in various control applications, including user dials and function selectors.

Seamless Integration in Electronics

The EC11 encoder suits audio systems, air conditioning panels, GPS units, and smart appliances. Whether adjusting volume, changing modes, or setting temperature, it enables accurate, repeatable control. Its sealed body helps block out dust and signal interference, which improves performance in high-use or industrial environments.

Multiple Configurations Available

We provide EC11 encoders in a variety of shaft lengths, detent steps, and resistance levels. You can customize encoder specs to meet your device’s electrical and mechanical requirements. For OEM projects or branded devices, we also support housing changes or PCB mount variations.

High Reliability in Long-Term Use

The encoder supports tens of thousands of rotational cycles with minimal degradation. The gold-plated contacts enhance conductivity and reduce wear. Its design minimizes bounce, ensuring stable signal output across all usage scenarios. Our strict production standards guarantee stable performance across batches.
