Positronic Improves Legacy
Connection with PosiBand Contact
June
2009—Closed-entry
female contacts are often used in D-subminiature connectors
to enhance performance and reliability. Closed-entry
contacts have an unbroken ring of solid material at the face
of the contact. In most cases, a sleeve is placed over a
standard “split-tine” contact to achieve the closed entry
feature. This design offers a degree of increased
reliability, but has inherent weaknesses.
Positronic’s new PosiBand® closed-entry contact is a
significant improvement over the legacy design, and
overcomes many of the weaknesses associated with the
“split-tine” and sleeve approach. The PosiBand separates the
mechanical and electrical function of the contact system.
The base contact provides a true closed-entry feature and
enhances electrical stability. The PosiBand spring clip
provides a more stable mechanical function.
Greater contact interface between male and female contacts
is achieved by this design when compared to the “split-tine”
design. The greater contact interface can provide greater
resistance to vibration and corrosion factors found in harsh
environments. Greater contact interface is achieved without
increased insertion force; in fact, the PosiBand system has
a lower average insertion force when compared to the legacy
design.
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 six contacts
energized. The currant rating for the size 22 contact is 10
amps, with six 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.
PosiBand contacts sell for the same price as the legacy
design. The price for a size 20 crimp-contact version is
.175¢ each at 30,000 pieces.
The PosiBand system is more robust than the split-tine
design, making it more suitable for harsh or high
reliability environments. 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.

Harwin Cuts Assembly Time with
Quarter-Turn 101Lok Datamate
May
2009—Harwin Inc. has launched 101Lok, a fast-mate version of
its secure, 2mm-pitch, J-Tek Datamate cable-to-cable,
cable-to-board, and board-to-board connector family.
Historically, secure mating has been achieved with the
Datamate J-Tek version using jack screws. New 101Lok
Datamate connectors require only a simple quarter-turn—101
degrees—to ensure complete security of the retention device.
101Lok connectors use specially designed hardware tensioned
by a coil spring to reduce the time required to mate the
connector halves. This is ideal for users that require
faster assembly, while ensuring complete security of the
retention device. This novel locking feature is also ideally
suited to Harwin’s mixed technology Mix-Tek Datamate
connectors, and also the Trio-Tek range, where
high-production volumes demand minimal assembly costs.
The spring tensioning also helps resist vibration in rugged
environment applications, such as aerospace. Bill Neukomm,
VP for sales and marketing at Harwin North America, said,
“These new 101Lok connectors are designed to be very easy to
use and require no special tooling. Our Datamate connectors
are chosen because they are very rugged and highly resistant
to shock and vibration. Now, with the introduction of these
101Lok Datamate variants, hi-rel users can speed up and
simplify mating, while still being assured of achieving the
performance they require.”
