Hirose DF40 Series Straight Surface PCB Header 30 Contact 0.4 mm Pitch 2 Row Shrouded

Hirose DF40C-30DP-0.4V(51) Straight Surface PCB Header is a precision engineered connector featuring 30 contacts in a 2 row configuration with a 0.4 mm pitch. It is designed for board-to-board and board-to-FPC interconnections, providing high contact reliability and a low profile, space-saving form factor.

The connector housing is constructed from durable liquid crystal polymer material that withstands temperatures from -35°C up to 85°C. It features a shrouded design offering protection against dust and short circuits by covering the contacts when mated. Its gold-plated copper alloy contacts ensure efficient electrical conduction and corrosion resistance.

Additional design features include nickel plated solder wicking barriers and a tactile locking mechanism that emits a click sound upon full mating, providing positive connection assurance. Guide ribs facilitate a precise self-alignment during assembly with a 0.33 mm tolerance, and shock-absorbing ribs enhance resistance to mechanical impacts and vibrations.

This connector series supports a range of stack heights between 1.5 mm to 4.0 mm, enabling flexible integration into compact electronic assemblies. Applications include mobile phones, development chip sets, LCD displays, notebooks, and keyboards where high-density, reliable PCB connections are essential.

The connector’s high density and low profile design maximizes PCB space utilization. Locking mechanism with audible click ensures secure mating and user confidence. Nickel plated barriers prevent solder wicking during mounting processes.

Shock absorbing ribs protect against mechanical stresses. The housing protects contacts from contamination and electrical shorts. Suitable operating temperature range broadens application capabilities. High contact reliability with effective mating length of 0.45 mm.

Self-aligning guide ribs provide precise connector engagement. Compatible with surface mount PCB assembly methods for efficient production.

Overall, the Hirose DF40C-30DP-0.4V(51) PCB header is engineered for demanding industrial and commercial electronic applications requiring compact, reliable, and durable interconnect solutions.
