How Machine Vision Cables Enable Real-Time Defect Detection
1. Introduction
Machine vision systems are the nervous system of modern manufacturing, inspecting products at speeds exceeding 10,000 units per hour. However, their performance hinges on the ability to transfer vast amounts of data—from high-resolution cameras to edge servers—without loss, latency, or corruption. Machine vision cables, optimized for bandwidth, durability, and signal integrity, are the lifelines that transform raw visual data into real-time quality control.
