The B2B-XH-A is the 2-circuit member of JST's XH series board-to-cable/wire header line. It carries tin-plated square pins rated 3 A and 250 V, mounts through-hole vertical, and uses a shrouded 4-wall housing with detent lock for secure mating.
Within the XH series the B2B-XH-A carries 2 positions against the 3 of the B3B-XH-A — the 2.50 mm pitch, through-hole mounting, and tin plating are shared across the series, so match the position count to circuit count.
