Semi-automated (with manual feeding) and fully automated (with automated feeding) solutions for using a vision system to evaluate shield trim quality on shielded cables. The vision system uses a multiplicity of cameras and a corresponding multiplicity of mirrors in order to achieve a 360-degree view of the cable segment to be inspected. Cables to be inspected are positioned in a repeatable location based on the strip length of the cable (where the edge of the cable jacket is located relative to the end of the cable). The processing system receives a live image feed from the camera system and then uses color and dimensional analysis of the acquired images to determine whether the shield trim meets quality control specifications or not.

An electromagnetic shielding material includes multiple strands of an electrically conductive yarn that are arranged as a braided, knitted, or woven mesh. Each strand of the electrically conductive yarn comprises one or more electrically conductive filaments; each electrically conductive filament comprises a core of a first electrically conductive material surrounded by a sheath of a second electrically conductive material different from the first electrically conductive material. The first electrically conductive material exceeds the second electrically conductive material with respect to electrical conductivity, while the second electrically conductive material exceeds the first electrically conductive material with respect to one or more of tensile strength, corrosion resistance, or one or more other mechanical or chemical properties or characteristics. In many examples, the first electrically conductive material includes copper and the second electrically conductive material includes stainless steel.
