FC8022M2. Deconstructed contact shown for
reference only.
PosiBand is more robust than split tine, which can be
pried open in harsh environments, resulting in reduced
normal force and degradation of electrical performance.
PosiBand has greater surface area at the male and
female contact interface, resulting in more consistent
electrical performance.
PosiBand has lower average inser tion forces, resulting
in greater ease in mating, especially in larger high
density connectors.The average lower inser tion force is
accomplished while meeting or exceeding performance
requirements.
The PosiBand’s main contact body does not require an-
nealing of the crimp barrels, as does the split tine de-
sign. This eliminates concern of unintentionally
heat-treating the mating end of the contact, which can
cause electrical failure.
PosiBand is qualified under SAE AS39029 specification.
PosiBand is also qualified under GSFC S-311-P4 to the
higher 40 gram contact engagement test requirement.
The PosiBand®contact system has many
advantages over the legacy split tine design.
For more information on PosiBand
closed entry contacts, see page 1 & 2.
