The HRS / Hirose DF56 Series is a compact 0.3 mm pitch micro-coaxial wire-to-board connector system. It is designed for vertical mating between a board-side SMT receptacle and a cable-side micro-coaxial plug. With a two-row staggered contact layout, metal shielding, multiple grounding points, and a compact mating structure, the DF56 Series is suitable for high-density signal transmission in compact electronic devices.
