Tested and qualified to MIL-C-28859 and MIL-C-28754 - Confirms the product meets specific performance requirements
Tuning fork and blade contact system - A proven technology for high reliability
Low insertion force (2.25oz/contact) - For easy mating
Rugged machined aluminum frames - Ensures excellent performance in harsh environments
Compliant pin press-fit, through-hole and flex circuit termination styles available - Support a variety of design application requirements
Tuning Fork and Blade
Contact System:
A proven technology for
high reliability.
Originally co-developed with the U.S. Navy, the NAFI Connector product
line includes multi-row, through-hole solder blade connectors and press
fit tuning fork backplane connectors. The highlight of the NAFI backplane
technology is its solderless “Dynamic Retention” gas tight, press-fit tuning
fork contact design. Rugged, metal header bodies are machined and
finished with chromate. Available in two, three, or four rows of contacts,
NAFI Connectors offer a high degree of design flexibility in order to meet
specific density and layout requirements.
Connector patterns containing multiple rows of contacts are easily
produced and can include standard NAFI-style features such as guide
pins and D-shaped polarizing keys. The mating backplane connectors
feature solderless press-fit tuning fork contacts arranged
on a 0.100” x 0.100” grid.

FEATURES & BENEFITS
0.100” x 0.050” staggered grid - High density optimizes trace routing through the backplane
Compliant press-fit termination of backplane connectors - Provides a gas-tight interface with the printed circuit backplane without
the need for soldering
Tuning fork and blade contact system - A proven technology for high reliability
Low insertion force (2.25oz/contact) - For easy mating
Daughtercard connectors feature surface mount termination via rigid pins or flex circuit - Maximum design flexibility depending on
the application requirements
Rugged machined aluminum frames - Ensures excellent performance in harsh environments
Low Insertion Force
(2.25oz/contact):
For easy mating.
The Ultra High Density (UHD) interconnect is a high reliability packaging
solution for airborne, space, shipboard, and ground-based applications.
With 80 contacts per linear inch, the UHD connector is tested and qualified
to DSCC 89065. These connectors feature up to 396 surface-mount
contacts in the SEM-E (Standard Electronic Module) format and up to 556
pins in the 10 SU configurations. The mating backplane connectors feature
solderless compliant press-fit tuning fork contacts arranged on a staggered
eight row 0.100” x 0.050” grid for optimized trace routing through the
backplane.
The module connectors are surface mounted to the module using rigid
pin or flex circuit terminations. Designers faced with unique packaging
requirements will appreciate the design flexibility of the UHD connector. A
modular approach allows for straightforward incorporation of signal, power,
coax, and fiber-optic inserts, as well as EMI shielding, all within the same
connector footprint. The design also enables the production of connectors
that are either longer or shorter than the basic SEM-E format. The UHD
connector is designed to provide signal integrity and interconnect density
to meet today’s advanced system-level requirements while maintaining a
robust design.
