What Makes Positronic’s
New “PosiBand®” Contact
Interface a Significant Improvement?
High reliability connectors utilize female closed entry contacts that provide
an unbroken ring of solid material at the face of the contact. The closed entry
feature is crucial in preventing damage to female contacts used in harsh
environments, repeated mating cycles, blind mate applications and applications
requiring highest reliability.
The most common closed
entry design utilized by
connector manufacturers is
a split tine and sleeve concept.
See figure 1. With this design,
both the mechanical forces and
electrical interface are provided only
at the tip of the female contact.
Positronic’s new PosiBand
technology takes a unique approach
to closed entry female contacts.
PosiBand contacts utilize a two-piece
contact design. See figure 2. Each piece serves a separate function, providing a
more mechanically robust contact and more consistent electrical performance.
The main body of the PosiBand contact provides a true closed entry opening to
enhance robustness. The PosiBand spring clip provides normal force on the male
contact. Consistent electrical performance is supported through a larger area of
contact interface between the male and female contact along the entire “floor”
of the contact body. PosiBand contacts are QPL listed under SAE AS39029 and
qualified under GSFC S-311-P4 to the higher 40 gram contact separation test
requirement.

Size 20 PosiBand Contacts
Initial Contact Resistance: 0.004 ohms, maximum.
Curve developed using Standard Density D-subminiature connectors load-
ed with size 20 crimp contacts terminated to size 20 AWG wire.
The PosiBand® contact system has many advantages
over the legacy split tine design.
7 PosiBand is more robust than the split tine contact, which can be pried open in harsh
environments, resulting in reduced normal force and degradation of electrical performance.
7 PosiBand has greater surface area at the male and female contact interface, resulting in
more consistent electrical performance.
7 PosiBand has lower average insertion forces, resulting in greater ease in mating, especially
in larger high density connectors. The average lower insertion force is accomplished while
meeting or exceeding performance requirements.
7 The PosiBand’s contact body does not require annealing of the crimp barrels,
as does the split tine design. This eliminates concern of unintentionally heat-treating
the mating end of the contact, which can cause electrical failure.
7 PosiBand is qualified under SAE AS39029 specification. PosiBand is also qualified under
GSFC S-311-P4/08 Rev C and GSFC S-311-P4/10 Rev C to the higher 40 gram contact
separation test requirement.
7 PosiBand is protected by US Patent 7,115,002.
For more details about the advantages of the PosiBand system, please view the detailed white paper at
www.connectpositronic.com/white-papers or visit our web site at www.connectpositronic.com.
