20-Position Center Strip Plug for Parallel Board Stacking
The Hirose FX2-20P-1.27SV(71) is a 20-position plug from the FX2 series, using a center strip contact arrangement for dense board-to-board interconnects. The 1.27 mm pitch and dual-row layout keep the footprint compact while routing 20 signal lines between parallel PCBs.
Surface-Mount Termination and Board Layout
Termination is solder-only, surface-mount, so the plug reflows onto the board without through-hole holes or press-fit tooling. The 1.27 mm pitch between rows and columns sets the routing channel width — a 20-position, dual-row SMT footprint fits within a roughly 12.7 mm by 5 mm keep-out, depending on pad and via escape.
