The photoelectric encoder module consists of two discs located across each other. There is a light source on one disc and two light-receiving elements (photoresistors) on the other disc. Between these disks, there is a moving disc with evenly spaced slits. By rotating this moving disc, the light receivers A and B are alternately connected and disconnected. So, a square wave will be generated at the outputs. If you count these pulses, you can calculate the amount of rotation. In addition, there is a phase difference of 90 degrees between the two outputs A and B, so we can find the direction of rotation by checking which output is ahead of the other.
