Aviation-Grade 120Ω Data Bus Cable

Aviation-Grade 120Ω Data Bus Cable

OVERVIEW
Aviation 120Ω data bus cable adopts gas plastic insulation and sheath, so that the cable has the characteristics of high and low temperature resistance (-60℃~+180℃), aging resistance and corrosion resistance, flame retardant, three-proof, light weight, small outer diameter and excellent mechanical properties, etc. The product GJB973A-2004, GJB773A-2000 and YD/T1019-2001 standard design and development, can be used in the The products are designed and developed in accordance with GJB973A-2004, GJB773A-2000 and YD/T1019-2001 standards, and can provide highly reliable service in harsh environments. They are suitable for signal transmission systems with matching impedance of 120Ω for avionics devices, 485 bus, CAN bus and other links.
