design basics Static, flexible, high-flex, continuous-flex - what's the difference? Unlike cables that you often see alongside home appliances or purchase from hardware stores like the one pictured below, high-flex and continuous-flex cables are designed specifically for moving applications. Continuous-flex cables are designed to operate inside cable carrier applications on automated or otherwise moving machinery. Unlike high-flex or flexible cables, continuous-flex cables are often seemingly very stiff, which is due to their engineered design and high-strength materials used to ward off breakage for millions of cycles. Continuous-flex cables are manufactured and sold in a massive range of types, sizes and quality levels, so performance can vary dramatically. This guide will walk you through the anatomy of a continuous-flex cable, the design guidelines that maximize performance and service life, R&D methods and testing procedures, and how selection and installation, partnered with design, can mean the difference between an application running a few thousands cycles and tens of millions of cycles of reliable performance.
