Encoders can be divided into two types according to their working principles: incremental and absolute. According to their own properties, they can be divided into photoelectric encoders and magnetoelectric encoders. Magnetoelectric encoders are a new type of angle or displacement measurement device. Its principle is to use magnetic resistance or Hall elements to measure the angle or displacement value of the changing magnetic material. The change in the angle or displacement of the magnetic material will cause a certain change in resistance or voltage. The change is amplified by the amplifier circuit, and the pulse signal or analog signal is output after being processed by the single-chip microcomputer to achieve the purpose of measurement.

However, the threaded rod needs to be rotated, fixed and disassembled by personnel, which makes the installation and disassembly cumbersome and inconvenient. Therefore, an encoder line connection structure is proposed to solve the above problems. Utility Model Content
