1.27mm dual row SMT pin header with post is a fine-pitch board-to-board connector designed for dense signal routing in modern electronic assemblies. This 1.27mm dual row SMT pin header with post uses two rows of square pins (0.40mm × 0.40mm) on a 1.27mm centerline spacing, providing a compact footprint while maintaining robust mechanical strength. The vertical 180° orientation and locating post (Ø0.80mm) ensure accurate alignment to the PCB during placement and reflow, reducing positional drift and solder-bridge risk.
