Signswise Incremental Optical Rotary Encoder for Arduino 600P/R Wide Voltage Power Supply DC 5-24V 6mm Shaft Quadrature

Works well

Used this for trim wheel control for MSFS2020.

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.

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...cant actually promise this) is open collector, so you can use a pull-up resistor to your controllers 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.

Perfect for what I needed. As described A++++

Used this to make a custom digital measuring wheel. Measurements were very accurate and its super simple to wire up.

Great item.

These have smooth effortless rotation, are seemingly precise and work as they were intended. Thumbs up. Make sure you us a pull-up resistor to signal terminals.

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.

This thing has no business being this good at this price. Smooth operation - 1440 pules per rev in standard quadrature configuration (2 phase). M3-.5 screws fit the mounting flange. Im feeding this thing 5 volts straight from USB, two encoders and a Teensy board drawing just .3 watts - whats to complain about.
