DF40 Series

Hirose's 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.
