The Hirose BM28B0.6-10DP/2-0.35V(53) is a 10-position, dual-row header with outer shroud contacts from the BM28 series, designed for board-to-board mezzanine stacking at a mated height of 0.6mm. The 0.014" (0.35mm) pitch is the tightest in the BM28 family, which means the PCB footprint demands careful trace routing — this is a connector for compact, high-density internal stacks in portable electronics, wearables, or module-on-board applications where every micron of z-height counts.
The gold flash (1.97µin) on the contacts is adequate for the typical 10-30 mating cycles inside a consumer or portable device; if your application requires frequent reconnection or field service, step up to a thicker-plate sibling in the BM28 family.
