Hirose DF40 Series Straight Surface PCB Socket 70-Contact 2 Row 0.4 mm Pitch Solder DF40

Hirose DF40 Series Straight Surface PCB Socket DF40 is engineered for high-density and low-profile electronic applications requiring reliable board-to-board and board-to-FPC connections. This surface-mounted socket incorporates 70 female contacts arranged in 2 rows with a 0.4 mm pitch solder termination, enabling fine pitch electrical interconnects in compact device assemblies.

The housing is crafted from robust Liquid Crystal Polymer which offers excellent mechanical strength while resisting thermal and chemical stresses encountered during manufacturing and operation. The socket features a maximum operating voltage of 30V and can safely carry currents up to 300mA, meeting typical low-power electronic requirements.

Designed with a 4 mm stacking height and guide ribs for self-alignment, the connector ensures precise, secure mating with a locking mechanism that produces an audible tactile click to confirm connection stability. Shock absorbing ribs reinforce the mechanical structure to protect contacts against vibration and impact damage.

Contact material is high-quality copper plated with gold to optimize electrical conductivity and reduce contact resistance. Nickel plated barriers minimize solder wicking, improving manufacturing quality. The socket effectively shields contacts from dust, debris, and shorting risks once mated.

This PCB socket operates reliably in a temperature range from -35°C to 85°C, making it suitable for a wide range of industrial, communications, consumer electronics, and computing applications.

This DF40 Series socket supports board-to-board and board-to-FPC connector systems. The compact 0.4 mm pitch and 2.38 mm row pitch provide high connection density for miniaturized electronic devices. Its locking and self-align features enhance assembly accuracy and reliability in automated manufacturing processes.

Common applications for this series include mobile phones, notebooks, LCD displays, developer chip sets, and keyboard interfaces. The DF40C-70DS-0.4V(58) model delivers proven performance in demanding miniature electronic product designs.
