8622 NAFI 2
Applications
Military airborne computer.
Description
• The NAFI 2 Series is a modular connector,
available either with 8 or 4 rows of contacts,
offering a very large diversity in the contact
number selection, from 16 up to 556 ways.
The connectors use improved miniaturized
tuning-forks and blade-contacts derived from
the MIL-C 28754 standard.
• One of the most interesting aspect of the new
8622 Series is the press-fit field proven tech-
nology. It provides a very low profile
female connector and contributes reducing
the volume and weight of the equipment and
making easier backplane repair.

• The male header is available with SMT one-
piece contact and flex-cable as well; both ter-
minations are interchangeable on the
daughter board.
Male and female connectors are available
also with straight solder spill or press fitted
terminations for parallel cards dispositions.
• The insulator modules are provided with
closed entry cavities for tuning-fork contact
protection during mating operation. Both
female end modules are fitted with standard
signal contact and polarizing keys. The end
modules are also available with AWG 16
cavities for power, coaxial or fiber optic of the
MIL-C 38999 Series II crimp contacts.

The 8622 connector series covers a large range of card formats, from the smallest SEM A1/B1 up to the 233 mm long DOUBLE EUROPE style.
In accordance with the number of modules, the above table shows the overall dimensions of the connector. The shortest connector is composed
of at least 2 modules. The longest, fitted with 14 modules, offers 556 contacts in a 197.90 mm length only.
From 2 to 10 modules, the male header is fastened on to the daughter card by 2 fixing points. Over 10 modules, a third center fixing is necessary.
Above table displays the connector flexibility. As an example, the connector ranges from 76 to 556 contacts for 8 row cavities totally equipped with
their contacts. The same 8 row modules may be underloaded in 6 rows only. In that case, the connector ranges from 56 to 416 contacts. On the
same way, a 4 row module connector fully equipped offers 36 to 276 contacts and only 16 to 136 as partially populated.
