Hirose Electric DF40 Connector Series

The Hirose Electric DF40 series connectors are slim FPC to board connectors that have a 0.4 mm pitch and 1.5 mm stacking height. They also feature a unique space-saving design, several stack heights available, strong contact forces and a reinforced structure.

DF40 series are slim FPC to board connectors that have a 0.4 mm pitch and 1.5 mm stacking height.

Space saving

The DF40 series has the world's shortest depth of 3.38 mm.

Higher density of the board-mounted components

The extremely small board mounting pattern and low above-the- board profile makes the connectors ideally suited for small device applications.

High contact reliability

Despite the connectors' small size and low profile the contacts provide strong contact forces and long contact wipe (0.45 mm), guaranteeing reliable electrical and mechanical performance.

Large self-alignment distance

The connectors will self-align within 0.33 mm.

Confirmation of the fully mated condition

Positive “click” sensation confirms correct insertion and connection of all contacts.

Built-in shock absorbing feature

The protrusions and indents in the insulator bodies protect the connectors from failures when exposed to sudden impact.

Solder wicking prevention

Nickel-plated barriers provide protection against solder wicking into the contact areas.

Contact area protection

External walls protect the exposed contact areas from intrusion of flux or foreign particles.
