EC11 Rotary Encoder W/ Push Button (Clearance)

This is a clearance item for the following reasons:

• Does Not Contain a Nut & Washer for mounting

Sorry for the inconvenience.

The EC11 is a compact incremental rotary encoder with a built-in momentary push button, making it ideal for DIY electronics projects requiring precise rotational input. It works seamlessly with Arduino, ESP32, and Raspberry Pi for applications like volume control, menu navigation, and parameter adjustment.
