Description

Technical Field

[0001] This utility model relates to the field of magnetoelectric encoder technology, and in particular to a magnetoelectric encoder that shields against magnetic interference. Background Technology

[0002] Magnetoelectric encoder: An encoder is a device that encodes signals (such as bit streams) or data and converts them into a signal form that can be used for communication, transmission and storage.

[0003] However, existing technologies still have shortcomings. Existing technologies require the use of magneto-electric encoders. There are many electronic devices in the manufacturing workshop, and the intermingling of electronic devices will generate magnetic interference. Magnetic interference will affect the operation of the magneto-electric encoder, making the working state of the magneto-electric encoder inaccurate or even unable to operate, thus reducing the working stability of the magneto-electric encoder.

[0004] Therefore, we propose a shielded magnetic interference magneto-electric encoder to solve this problem. Utility Model Content

[0012] Preferably, the magneto-electric encoder body is fixed to the inner surfaces of the first and second outer shells by a first extrusion plate and a second extrusion plate.

[0013] In this utility model, a shielded magnetic interference magneto-electric encoder is provided.
