Rotary encoder 20mm with pushbutton

A rotary encoder can be rotated endlessly – it has no end. That’s the main difference between it and the potentiometer and the reason why it’s more suitable for usage in certain applications. Its output (rotation outcome) is written in gray code, therefore you’ll need a microcontroller in order to use it.

It also has inbuilt pushbutton which makes it suitable for different selections.
