With the continuous improvement of the speed of rail trains, the existing train signal transmission system is vulnerable to external factors, resulting in the instability and inaccuracy of signal transmission.
In order to reduce the adverse impact of ultra-high-speed driving environment on train signal transmission, the hybrid D-sub connector developed and produced by TXGA has a gold plating of 0.75 μ m on its contact parts, and its contact performance is more stable. After special treatment, the plug shell can shield EMI/RFI interference in all directions and provide more stable and high-quality signal transmission for rail trains in ultra-high-speed operation.
