Hongyan Technology EC11EBB24C03 Dual-Axis Encoder with Switch 15-Pulse

The encoder provides a standard quadrature output (two channels, A and B) for detecting rotation direction and speed. It also has a separate two-pin output for the integrated push-button switch, which acts as a simple momentary contact closure.

The specification indicates 15 pulses per detent. The total pulses per full 360-degree rotation depend on the number of detents in the mechanical assembly, which is a standard 12 or 24 detents for many EC11-style encoders, resulting in 180 or 360 pulses per revolution respectively.

Yes. The encoder's switch and quadrature outputs are simple mechanical contacts and can be used with standard GPIO pins on 5V or 3.3V systems. It is recommended to use internal or external pull-up resistors on the input pins for reliable signal reading.

This component is ideal for integrated control interfaces where both rotary selection and a confirmation/selection button are needed. Common uses include multimedia volume/playback controls, parameter adjustment knobs on instrument panels, and navigation interfaces in embedded systems.
