The latest series of wire-to-board, crimp style disconnectable connectors, claimed to provide optimum performance in high vibration conditions, have been introduced by JST. The PBV connectors are compact with a low profile and a 2.0mm pitch.

These SMT connectors are available in side- and top-entry configurations. The connectors are suitable for consumer, commercial and industrial applications where vibration might occur. They have a secure locking feature to prevent contact stubbing and back-out when mated. The positive locking system fits inside the envelope of the header making it possible to stack the headers close together and still be able to release the positive lock.

The connectors are available in 2 to 15 circuit sizes rated 3A (using 22AWG) at 100V. Wire sizes 22 to 28AWG are accommodated. The temperature range is -25 to +85°C, including temperature rise when applying an electrical current.

The SMT headers are moulded in a RoHS-compliant 94V-0 polyamide resin. The socket housing is PA 66, UL94V-0 rated nylon and contacts are phosphor bronze, tin-plated. Mating shrouded headers for top and side entry provide sufficient flat surface for vacuum gripping equipment, says the company.

Contacts are offered on standard size reels for semi-automatic or fully automatic application tooling while mini-reels are offered for mini-reel hand tools. SMT headers are provided on embossed tape for automatic insertion equipment.
