Technical Specifications Composite multi‑conductor structure, includes power core and signal shielded core. Matched dedicated plug‑in connectors at both ends. Operating temperature ‑20 ℃ to +80 ℃, storage temperature ‑40 ℃ to +85 ℃. High‑flexibility anti‑fatigue outer sheath for continuous bending motion.
Functional Features Transmits servo motor driving power from control cabinet to robot arm. Transmits encoder position feedback signal from robot joint back to control cabinet. Shielded structure suppresses electromagnetic interference for signal lines. Dedicated connectors guarantee stable electrical connection during robot continuous swinging motion.
Application Scenarios Replacement spare‑part for ABB industrial robot mechanical unit. Used for robot cable aging, wear‑out and damage replacement on automated production site.
Performance Parameters Excellent bending fatigue resistance for repeated robot joint movement. Low signal attenuation for feedback loop. Stable connector contact performance under mechanical vibration environment.
Material Composition High‑flexibility copper conductor. Multi‑layer shielding structure for signal wires. Tensile‑reinforced inner layer. Wear‑resistant and oil‑resistant flexible outer sheath. Precision molded plug‑in connectors at both ends.
Structural Characteristics Integrated finished cable harness with fixed length. Both ends assembled with dedicated robot connectors. Outer sheath provides mechanical and chemical protection. Weight approximately 1.1 kilogram.
Working Principle Motor driving power is transmitted through power conductor from control cabinet to robot joint motor. Encoder position signal is transmitted back to control cabinet via shielded signal conductors. Cable harness follows robot joint movement to complete continuous power and signal transmission.
Installation Requirements Confirm robot total power is fully disconnected before replacement. Remove old cable harness along robot body routing path. Install new 3HAC2091‑1 cable harness according to original routing. Firmly lock connectors at cabinet side and robot arm side. Reserve reasonable bending margin for robot full‑range movement. Power on robot and verify motor driving and encoder feedback function.
