8602 NAFI
Description
Applications
Military airborne computer
• NAFI board-mounted connectors are used as
interface between daughter-boards and back
planes or between two adjacent daughter-
boards.
• The connector support is of light alloy. It is dril-
led to a 2.54 x 2.54 mm (.100 x .100)
matrix accommodating contacts housed in
modular insulators with one, two or four
contacts. On assembly, the blocks form inter-
connections of different length and width.
• The daughter board is generally associated
with a male header. The male header is an
aluminum alloy extrusion holding blade
contacts for solder angle and straight spill ter-
mination.

• The system is highly flexible.
Aluminum alloy is robust, light, simple and
may be machined accurately.
• The association of blade and tuning fork
contacts is a simple design, highly efficient
under severe vibration.
• Contact numbers : from 10 to 300.
