Hirose – Wire-to-board connectors for power supplies feature 1.2mm pitch


Hirose’s DF58 is a series of space- saving, low-profile, wire-to-board connectors for miniature applications. It consists of crimp sockets and headers in a single row.

The low mated height profile is just 1.0mm, and the depth is 4.97mm, reducing the space required on the board to accommodate power connections.

Although Hirose has kept the connector’s dimensions to a minimum, the power rating is not compromised. A high current rating of 3A, when using the two-contact version with 28 AWG cable, enables the DF58 to support power-supply applications.

Secure connection is guaranteed with the Vertical-insertion Swing- extraction (ViSe) double-locking mechanism. The crimp socket is mated to the header in a vertical direction; it is guided in at an angle, however, to engage with the positive lock. This ensures high retention force in the upper direction and prevents the cables from being easily disconnected.

A friction lock prevents incomplete locking and floating after mating.

Highly reliable two-point clipping contacts are used to keep the contact resistance stable and to reduce temperature rise.
