Greater contact interface between male and female contacts is achieved by this design when compared to the “split tine” design. Greater contact interface can provide greater resistance to vibration and corrosion factors found in harsh environments.
PosiBand contact resistance is 3 milliohms for size 20 contacts and 4 milliohms for size 22 contacts. The current rating for size 20 contacts is 14 amps with 6 contacts energized. Size 22 contact currant rating is 10 amps with 6 contacts energized. Both were tested per U.L. 1977.
In addition, PosiBand contacts do not require annealing of the crimp barrel. This eliminates the possibility of unintentionally annealing the mating end of the female contact, which can cause intermittent or open electrical circuits.
The PosiBand system meets or exceeds performance requirements of SAE AS 39029.
This new contact system is now available in standard density, high density and combination D-Subminiature connectors and is also used on many new D-Subminiature offerings, such as the high density Combo-D connector.
