Classification of specialized cables for industrial robot motion control and power supply. Includes power cables for power transmission to each axis of robot arms, encoder cables for encoder signal transmission, control cables for control signals, and harness cables for end-effector connections. Features special construction with high flexibility, torsion resistance, and oil resistance, providing durability for continuous robot operation. Distinguished from general industrial cables and wiring materials by robot-specific design offering high mobility and reliability. Used for inter-axis wiring in articulated robots, SCARA robots, and Cartesian robots, as well as connections to robot controllers.
