Magnetic encoder！

Encoder is the core technology to provide location information.
• Optics, using mask and phase array technology
• Magnetic principle
The main difference between these two encoders is the position signal acquisition mode. Understanding the principle of the two encoders is useful in deciding what type of encoder to use.
Magnetic encoders, also known as magneto-electric encoders, are a new type of angle or displacement measuring encoder device that uses magnetic relays or Hall elements to measure the angle or displacement of varying magnetic materials. Magnetic material angle or displacement changes will cause a certain resistance or voltage changes, through the amplification circuit to amplify the change, through the single-chip processing output pulse signal or analog signal, to achieve the purpose of measurement. Magnetic encoder structure is divided into sampling and amplification of the two parts of the output, the use of detection generallvey used to complete the bridge circuit, a half-bridge and full-bridge two, amplified output generally through the transistor and op amp and other devices to achieve
