2 mm DF59 Series Multi-Functional, high performance SMT receptacle header connectors with a compact space saving design and a low profile mating height of 2.48 mm. These header connectors are able to provide wire to board, board to board and short circuit pin connections to the PCB offering design flexibility. These DF59 SMT header connectors use a swing lock mechanism when used in wire to board connections which incorporates both positive and friction locks. A positive locking mechanism secures the header to the receptacle providing a tactile click when the lock is securely engaged. A complete electrical connection is then made by the friction lock mechanism which also produces a tactile click when fully engaged. This swing lock mechanism provides a secure connection and prevents accidental unmating caused by severe wiring and mechanical stress. The contacts of these DF59 series receptacle header connectors have a two point contact design for a reliable electrical connection. These DF59 SMT headers will mate with the DF59 Series male crimp housings, short circuit pin connectors and floating board to board connectors.

These 2 mm DF59 Series Multi-Functional Connectors are ideal for use in LED lighting applications

Hirose DF59 Series

The Hirose DF59 series features a low profile design that minimises shadowing and a positive swing-lock engagement, which provides strong plug retention against cable pull. Additionally, the Hirose DF59 series offers a floating board-to-board connector which allows ± 0.5mm floating function in XYZ directions, reducing contact stress. With the Hirose DF59 series, multiple board-to-board connections are possible, minimizing the issue of thermal expansion and reducing component quantity. Applications include LED lighting, power supplies, battery connection and small DC motor drives.
