Overview
The B5B-XH-A is the 5-circuit member of JST's XH shrouded header line, designed for board-to-cable/wire connections. Rated 3 A at 250 V with tin-plated mating contacts, the header mounts vertically through hole and uses a detent lock for secure mating.
Series & positions
Within the XH series the B5B-XH-A carries 5 positions against the 4 of the B4B-XH-AM — the 2.50 mm pitch, 3 A rating, and through-hole vertical orientation are shared across both parts, so match the position count to circuit count.
