A few grams of cable rarely look important on a drawing, but they can matter once that cable is routed through a camera gimbal, robotic joint, medical imaging head, AR/VR device, UAV payload, or compact display hinge. In these systems, cable weight can influence inertia, drag, connector loading, routing force, available space, and even how smoothly a moving module behaves. That is why engineers searching for micro coax cable weight usually need more than a single catalog number.
