Twinaxial cabling, or "Twinax" is a type of cable similar to coaxial cable, but with two inner conductors instead of one. This cable offers very-short-range, high-speed differential signaling applications. Manufactured with optimum flexibility, shielding, and performance. Outer jackets are PFA (Perfluoroalkoxy) . Dielectric and fillers made of PTFE (Teflon). Temperature range of -30°C to +80°C. All values without tolerances are nominal unless otherwise stated.
