I. Main Features

20320-R40T-11 adopts a 0.5mm spacing and right-angle vertical mating structure, with a pairing height of only 4.3mm, making it particularly suitable for miniaturized designs. It supports high-speed signal transmission with eDP HBR2 (5.4 Gbps/Lane) and USB 3.0 Gen1 (5 Gbps), and has a latching feedback to confirm connection stability. The product is compatible with AWG #40, #38, #36 and other miniature coaxial cables, as well as double coaxial and discrete wiring materials. The structural design can effectively prevent solder paste overflow, ensuring welding quality.
