Encoder introduction

An encoder is a device that compiles and converts a signal (such as a bit stream) or data into a form that can be used for communication, transmission, and storage. The encoder converts the angular displacement or the linear displacement into an electrical signal. The former is called a code wheel, and the latter is called a code wheel. According to the readout mode, the encoder can be divided into two types: contact type and non-contact type. Contact type uses brush output. A brush contacts the conductive or insulating region to indicate whether the state of the code is "1" or "0"; the non-contact receiving sensitive component is a photosensitive component or a magnetic sensing component, and the light transmitting region is opaque when the photosensitive component is used The light zone indicates whether the state of the code is "1" or "0". The binary signal of "1" and "0" is used to convert the collected physical signal into machine code readable electrical signal for communication, transmission and store.
