50-position unshrouded header at 0.100-inch pitch
The 0.100-inch (2.54 mm) pitch sets the board footprint — every 50-position through-hole pattern on the PCB lines up with this grid. LCP also handles the reflow peak during wave-solder assembly without the housing softening or the pins shifting.
Unshrouded push-pull header — no polarisation wall, so the mating receptacle must have its own keying or the assembler aligns by sight. Square male pins, copper alloy, 0.318-inch (8.08 mm) mating length — mates with standard AMPMODU Mod II receptacles and crimp-socket housings. The 0.100-inch row spacing matches the same grid as the pitch, so a 2×25 receptacle lines up pin-for-pin.
