Encoders are a type of motion control sensor that provides feedback to the control system. Specifies the position of individual elements, angle of rotation, speed, acceleration, direction of movement, and distance. We can divide encoders according to the specificity of the output signal. We distinguish between incremental and absolute encoders. Absolute encoders remember the current position even after the power is turned off. The described encoders generate a code signal, which in an analog form informs about the exact parameters of each position. Whereas, incremental encoders measure the angular position by counting the pulses placed on the dial.
