Horizontal Mating Connectors Handle High Current

A horizontally mated two-piece connector from Hirose, the DF64 Series, is made available for board-to-board and board-to-wire interfaces. The two-position connector measures 20.4 x 14.4 mm and has a mated height of just 4.7 mm. Developed for higher power applications, the DF64 uses 18-24 AWG wire and can carry 5 amps of current.

Unlike conventional horizontally mated connectors that require a different series of connectors between board-to-board and board-to-wire interfaces, the DF64 Series features a common receptacle that mates with the header and the cable plug. As a result, manufacturers using the DF64 Series can simplify their assembly and eliminate the time and cost needed to maintain inventory of any additional components. In addition, the DF64's simplified assembly provides high connection reliability while enabling easy and efficient repairs when necessary.

The connector has an effective mating width and length of ± 0.5 mm in the X direction and 2 mm in the Y direction. This allows the connector to compensate for manufacturing tolerances and thermal expansion in use. · The enclosed contacts in the housing maintain contact integrity and reduce danger to the operator from accidental finger contact. · Long creepage distance (3.2 mm MIN) helps prevent arcing. · The friction lock on the board-to-board interface provides the strength and retention needed to ensure a secure connection.

The Hirose DF64 Series connectors are UL Recognized and they carry a voltage rating of  350 Vac/Vdc. They are RoHS compliant, halogen-free, and are capable of operating at 105 °C.  Typical applications include LED lighting, medical devices, copiers, factory automation controllers and general board to wire connections.
