Absolute Encoders

Absolute encoders are sensors that directly output digital quantities and are often used in motor positioning or speed measurement systems. The working principle of absolute encoder and incremental encoder is very similar, the main difference lies in how the position is determined: the position of the incremental encoder is determined by the number of pulses counted from the zero mark, while the absolute encoder The position of the sensor is determined by the reading of the output code, and the reading of each position within one revolution is unique. Therefore, when the power is disconnected or the code wheel is shifted, the absolute encoder will not lose the actual position.
