5V operation is hit and miss
2BCFrankReade✓ Verified Purchase•September 10, 2023
Learned this the hard way - Not always reliable on 5V. We use a lot of these, and we always do 12V nowadays. The nice part though, is that the output is (well...can't actually promise this) is open collector, so you can use a pull-up resistor to your controller's voltage, which might be 5V, and run your inputs like that while still powering it by 12V. Check your individual encoder though, because only god knows how the PCB inside is configured, or you..if you open it or measure the outputs on a meter.
Very Smooth

This is a very nice rotary encoder. I purchased this, along with a beautiful machined aluminum knob, for a hobby project. For quick breadboard projects it is not as convenient as a cheap rotary encoder you can plug into a breadboard, but the feel of this encoder makes it well worth the slight inconvenience. I have used it for Arduino and FPGA projects and will always use this rotary encoder over the cheap ones.
If I could suggest one improvement it would be to add pin headers to the power and IO pins. It was easy enough to add these myself. Attaching pin headers makes it easy to use with a breadboard or Arduino header.

Excellent

Love it. Should have picked up some of these years ago...will be bookmarking for the future.
Easy to integrate with an Arduino following the instructions from other reviewers/answerers on this page.
I accidentally dropped the small wooden box I mounted this in from about 36" onto carpet. Still works fine.

Accurate on Arduino 5V - missing pulses fixed in code
JC✓ Verified Purchase•August 2, 2023
I used the example code in the questions/answers section of this page, and the arduino was missing pulses. Sometimes the counts would sporadically go backwards. Slow revolutions would give hundreds of counts per revolution, but fast revolutions would give 30 counts.
I found a code example on github using attachInterrupt which fixed the missing pulses. Reference and code attached in picture along with a simple wiring diagram. Now I get 1200 counts per revolution repeatably (due to counting both A and B phase changes).
I've tested this for a day and am pleased with the results so far. I am adding this into my project shortly and will update after more use.

great encoder for the price

The media could not be loaded. I am using this with an arduino DIY preamp as a volume control (of all things).
there is nothing else like this on the market; its really good and now, its affordable.
you need 4.7k pullups on the A and B lines. give the unit 5v and its normal quadrature after that.
see my photo and video for a demo of what it can be like if you integrate this part into your system.
