Technical Field

[0001] The utility model relates to the technical field of encoders, in particular to an encoder with an efficient heat dissipation effect. Background Technique

[0002] An encoder is a device that encodes signals or data and converts them into signal forms that can be used for communication, transmission, and storage. An encoder converts angular displacement or linear displacement into an electrical signal. An incremental encoder converts displacement into a periodic electrical signal, and then converts this electrical signal into a counting pulse, and the magnitude of the displacement is represented by the number of pulses.

[0003] When an incremental encoder works, it will generate heat. The heat generated by the existing incremental encoder is dissipated from the inside to the outside through the housing. However, the housing is integrated and made of plastic, so the heat dissipation has limitations.

[0004] In view of this, we propose an encoder with an efficient heat dissipation effect. Content of the Utility Model
