Incremental Optical Rotary Encoder for Arduino 360P/R Wide Voltage Power Supply DC 5-24V 6mm Shaft Quadrature

Using this an encoder for older games that support this type of controls. Seems to work fine when used in conjunction with an "Pro Micro" board.

Using these with arduino for position control. They work as advertised, although they will not be accurate down to a thousandth, which I did not need, they are well constructed and with the use of interrupts, don't miss much as far as movement goes. Will say a recommended buy when exact accuracy is not a necessity.

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.

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.

It works great for my purpose, bench testing.

Using the code in other reviews, made a tool to measure smooth concrete beams 150ft long. Very repeatable, very pleased. Purchased with rubber wheel and encoder bracket and both fit well.

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. Essentially, you need to protect the transistor inside the device from frying as it grounds the incoming signal voltage through the collector/emitter junction.

Yellow = A phase, Blue = B phase, Red =Vcc power +, Black = V0 There is no yellow wire should change the connection description.
