Low-profile wire-to-board connectors ideal for space-constrained designs

DF58 series connectors from Hirose offer a current rating of up to 3 A for use in power-supply circuits. They provide highly reliable mating operations and secure connections.

The DF58 series of wire-to-board connectors from Hirose save space and reduce height in wearable, portable and other space-constrained designs. The series consists of crimp sockets and headers in a single row. 

The mated height profile is just 1.0 mm. Depth of 4.97 mm reduces the space needed to assemble the connector on the board, yet the DF58 still provides a long effective mating length of 0.29 mm.

Despite the DF58’s small size, a high current rating of 3 A, which is feasible with the two-contact version and 28 AWG cable, support power-supply applications.

The Vertical-insertion Swing-extraction (ViSe) double-locking mechanism provides for secure connections. The crimp socket is mated to the header in a vertical direction, but is guided in at an angle to engage with the positive lock. This ensures high retention force in the upper direction, and prevents the cables from being easily disconnected. The friction lock prevents incomplete locking and floating after mating.

Highly reliable two-point clipping contacts stabilize contact resistance and minimize the rise in temperature in operation.
