Description: This is a 12-step rotary encoder with a nice ‘clicking’ feel. It’s breadboard friendly, and has a pretty handy select switch (by pushing in on the knob). The encoder is different from a potentiometer in that an encoder has full rotation without limits. The unit outputs gray code so that you can tell how much and in which direction the encoder has been turned.
This unit does not come with a knob, but a working knob is related below.

Rotary Encoder is well made and works well.
I got this as a general purpose rotary encoder to go in my prototyping box. The linked tutorials make it real easy to get up and running quickly. If you want to be able to add / remove this to a breadboard I’d recommend making your own breakout board for it as the pins are soft and break pretty easily. If you’re just going to panel mount it then you should be good to go. I’d get/use a knob with this as the actual shaft is pretty small making it harder to grip than the sort of potentiometers you get for hobby electronics.
