Description: This 1024 pulse per rotation rotary encoder outputs gray code which you can interpret using a microcontroller and find out which direction the shaft is turning and by how much. This allows you to add feedback to motor control systems. Encoders of this kind are often used in balancing robots and dead reckoning navigation but it could also be used as a very precise input knob.

I built a persistence of motion LED display for a wall clock using one of these bad boys. It has great precision and very little resistance or inertia, so it worked great for my project. The only problem is that it seems to have lost accuracy over time. I believe I put too much stress perpendicular to the axle. If you use one of these you should take care to reduce stress on the axle.
The measurements are metric, so it was slightly difficult to find a 6mm bolt to mate with the axle at my hardware store.
Four stars because it operates within its advertised limits but I wish it was just a little sturdier for my project. I’m going to buy another one and hope that I damaged it during construction or transportation and not regular use.
Overall good encoders, they are a bit larger than I was expecting, but that’s not really an issue. Overall they are pretty robust and work great in pair with the sabertooth and kangaroo motor controller combo. For this price you can’t really beat the performance.
