HN3808-AB Rotary Encoders Features A photoelectric rotary encoder is an electromechanical device that has an internal shaft inside a cylindrical space that looks like an motor. The circular plate inside it has two slits. An optical transmitter sensor is located on one side and an optical receiver sensor is located on the other side. When a gap is placed between the two sensors, the sensors and finally the receiver are connected to the microcontroller. Rotary encoder is commonly used to determine the positio...
