This arrangement was originally
developped for military applications.
Due to the rigidity of the cables
used, the front male insulator has
been reinforced to maintain a perfect
alignment of contacts during mating.
A header is placed in the backshell
to guide each wire and to guarantee
tightness even when cables
are bent. Available in Mil-DTL-38999
series III standard.
