Hirose DF40 Series Straight Surface PCB Header, 80 Contacts, 0.4 mm Pitch, 2 Row, Shrouded DF40

Hirose DF40 Series Straight Surface PCB Header, model DF40, is a high-density, 80-contact connector with 0.4 mm pitch and 2 rows. This shrouded header connector is designed for reliable board-to-board and board-to-FPC connections with enhanced protection and precision.

The header's liquid crystal polymer housing offers a compact low-profile solution with a minimum width of 3.38 mm, maintaining sufficient vacuum area for pick and place mounting. The contacts are gold plated copper alloy with nickel plated barriers to prevent solder wicking and ensure consistent electrical contact.

This connector incorporates a locking mechanism that produces a tactile click upon mating, confirming secure connection. Guide ribs enable self-alignment within 0.33 mm, improving assembly reliability. The reinforced structure equipped with shock absorbing ribs protects against mechanical stresses such as vibration and impact during operation.

The shrouded design covers contacts when mated, preventing dust ingress and short circuits. SMT leads are placed close to the connector to reduce contamination risks. It supports an operating temperature range from -35°C to 85°C and is rated for 30 V and 300 mA current.

Ideal applications include miniature electronic devices like mobile phones, LCD displays, notebooks, keyboards, and developer chipsets. Hirose DF40 connectors provide versatile stack heights from 1.5 mm to 4.0 mm, enabling design flexibility and high density mounting.

High density, low profile design suitable for compact electronic applications. Nickel plated barriers prevent solder wicking ensuring contact reliability. Locking mechanism with audible click offers superior mating assurance.

Guide ribs enable precise connector self-alignment during mating. Reinforced structure with shock absorbing ribs protects from impact and vibration damage. Shrouded housing safeguards contacts from dust and prevents shorts.

Wide operating temperature range from -35°C to 85°C. Surface mount type for easy PCB integration. Compatible with board-to-board and board-to-FPC systems. Gold plated copper alloy contacts provide superior conductivity and reliability.
