This speed encoder disk is used with encoders to measure the speed of motors etc. These units work great with our Infrared Speed Motor Sensor
The openings .in the disk make it possible for an infrared sensor to count the openings as the infrared shines through them. They are an ideal fit for our Robot Wheel and Motor for Arduino if you want to build your own robot.
