[0002] An encoder is an electronic device whose main function is to convert angular displacement, linear displacement or other forms of motion in the physical world into a usable signal form for processing and transmission in digital signal processing and communication systems. Specifically, the encoder can convert raw data into a character sequence or a binary code sequence, thereby realizing the digital expression of information.

[0003] In practical applications, encoders are widely used in many fields such as industrial automation, precision machinery, satellite navigation equipment, etc. They can help measure the position, speed or direction of an object and provide feedback signals, which are crucial for the control system. During use, it was found that the installation and disassembly of the existing rotary encoder and the fixed plate are complicated and inconvenient, which makes it inconvenient to repair the rotary encoder and affects the coordination between the internal code disk and the light-transmitting hole. For this reason, we urgently need to provide a rotary encoder. Utility Model Content

[0012] As a preferred solution, a mounting cover plate is fixedly connected to the outer wall of the threaded column, so that when the rotary encoder is used, the mounting cover plate and the encoder housing can be easily assembled.
