The encoder
| |
An encoder is a device that encodes a signal (such as a bit stream) or data and converts it into a signal form that can be communicated, transmitted, and stored. < a href = "" https://baike.so.com/doc/593521.html" "> make up < / a > decoder to angular displacement or linear displacement is converted into electrical signals, the former is called the encoder, which is referred to as a yardstick. According to the readout mode, the encoder can be divided into contact type and non-contact type; According to the principle of operation, encoders can be classified as incremental and absolute. The incremental encoder converts the displacement into periodic electrical signals, which are then converted into counting pulses, with the number of pulses representing the displacement. Each position of the absolute encoder corresponds to a definite numerical code, so that its indication relates only to the starting and ending position of the measurement, and not to the intermediate process of the measurement. |
