Because absolute encoders are significantly better in positioning than incremental encoders, they have been increasingly used in industrial positioning. Absolute encoder because of its high precision, the output bits are more, such as still using parallel output encoder, each bit of the output signal must ensure that the connection is very good, for more complex conditions but also isolated, connecting cable core number, thus So that the absolute inconvenience and reduce the reliability, therefore, the absolute encoder in the multi-bit output type, are generally selected serial output or bus-type output, production of absolute encoder serial output is the most commonly used SSI encoder (synchronous string Line output).
