Photoelectric encoder is a device used to measure the rotation motion, and the rotation angle and speed are measured by the interaction between photoelectric sensor and encoding disk. Among them, ppr is an important parameter of photoelectric encoder, which indicates the number of pulses per revolution.

1024ppr means that the photoelectric encoder outputs 1024 pulse signals per revolution. This means that the photoelectric encoder will output 1024 pulse signals in one rotation, which can be used to calculate the rotation angle and speed. Generally, the higher the ppr, the higher the accuracy of photoelectric encoder, which can measure smaller rotation angle and faster rotation speed.

Photoelectric encoders are widely used in mechanical equipment, automation control, robots and other fields, which are used to measure the rotation angle and speed and realize accurate position control and motion control. In industrial production, the application of photoelectric encoder can improve production efficiency and product quality, reduce manual operation and mistakes, and improve the level of production automation.
