Rays Twinaxial Cable RS 485 Cable
Product Introduction：
The aviation RS 485 data bus cable employs fluoroplastic insulation and sheathing, featuring high- and low-temperature resistance, aging resistance, corrosion resistance, flame retardancy, lightweight, small outer diameter, and excellent mechanical toughness. It ensures stable performance and maintains constant signal propagation speed across a wide frequency range.It is primarily used in aviation electronic systems, AFDX aircraft data networks, and military communication data networks.
This product is a direct replacement for Belden 1813A, MOGAMI W2997 and Alpha Wire 1102 series.
