Background

An encoder is a device that compiles, converts, and/or formats signals or data into a form of signals that can be communicated, transmitted, and stored. The encoder signal is transmitted out through the cable, and the transmission quantity of the signal is greatly influenced by the performance of the cable. The existing encoder cable is generally composed of a signal insulation wire core, non-woven fabrics, a tinned copper wire braided shielding layer and a polyvinyl chloride sheath, or cotton yarn is filled in the middle of the signal insulation wire core. According to the encoder cable with the structure, the signal wire core is in the middle, and stress can not be diffused outwards through long-time extrusion, so that the wire core is easy to break.
