The JST B2P-VH-TW is a 2-position inline adapter from the VH series, converting one receptacle to another — both ends accept female sockets. It's a free-hanging (in-line) part, so it sits in the wire run, not on a board.
Terminal Compatibility and Current Rating
The B2P-VH-TW accepts standard VH series crimp terminals — the same female contacts used in the VH receptacle housings. No special tooling beyond the usual VH crimp applicator is needed. The current rating for the VH series is determined by the crimp terminal and wire gauge, not the adapter body itself; the adapter passes the full rated current of the terminal pair.
