Encoder

Encoder is a device that converts angular or linear displacement into a signal, which can be used for communication, transmission and storage. Encoders have many kinds of classification form:
1. According to the engraving way of coding disc: Incremental encoder and absolute encoder.
2. According to the signal output type: Voltage output, open-collector output, push-pull output and line driver output.
3. According to the encoder mechanical installation form: Shaft encoder, blind shaft encoder, hollow shaft encoder.
4. According to the encoder working principle: Optical encoder and magnetic encoder.
