Ultraflex is a light weight high performance cable that exhibits excellent resistance to rough handling. The smooth PVC jacket is ultra flexible, and coils easily. 100% oxygen free copper is used for the leads and spiral shielding for ultra-low capacitance. A conductive PVC shield encases the primary insulation and center conductor, which reduces handling noise. A heat shrink insulation is used for strain relief, which helps prevents solder joints from breaking and fully insulates the connection terminals.
