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.
