Description: Rotary encoders can be used similarly to potentiometers. The difference being that that an encoder has full rotation without limits (It just goes round and round). They output gray code so that you can tell how much and in which direction the encoder has been turned. They’re great for navigating menu screens and things like that. This encoder mounts at a right angle so it’s perfect for things like control panels and rack-mount enclosures.

This encoder is especially cool because it has a common anode RGB LED built in, as well as a push-button. Look below for the clear knob that goes with this potentiometer.

  • As per the data sheet the row with 3 pins seem to be 2.5mm spaced but the row with 5 pins is 2mm spaced. And the two rows are 3.1mm apart. So ignoring the 2 non-signal tabs, will the other pins fit on a bread board? Perhaps with a little bending?

  • There no eagle footprint for this ?

    • I was going to say “sure there is”, but that’s for the upright one. Here’s a library with a single Device with the right angle package, based on SparkFun-Electromechanical.lbr/ENCODER_RGB_CA which only had the upright package. The only electrical difference is the addition of a NC pin connected to the two structural support pads, in case you want to do any grounding of them. The Document layer contains secondary package outlines. Please keep in mind that I don’t have this part, and those dimensional drawings are conflicting, but the pad layout should be fine. github:EagleWorks - COM-10984.lbr

      • Do you still have the footprint for this? I tried your filedropper link, but get redirected to an ‘upload’ screen. Thanks.

        • Hi there! Thanks for the heads-up. It now has a somewhat more permanent place in my (mostly empty) github repository; . On that page, right-click ‘Raw’, and save the link :)

  • Something like this (right angle mount) without RGB and with built-in push button switch on the shaft would be great…
