Cannon Trident Connector System
Contacts
General recommendations for the selec-
tion of Trident contacts are listed below.
Platings: Tin is recommended for most
applications. It is cost effective and
matches well to most wires. Gold is pre-
ferred for special situations. Gold resists
oxidation, has high surface conductivity,
and has a low coefficient of friction.
These features make gold the preferred
plating for low level signals (a rule of
thumb is <100 mA), corrosive environ-
ments (for unsealed connectors), and for
increased mating cycles. The electrical
performance of the contact is determined
at the surface of the contact. For this rea-
production. Machined contacts offer
son, flash gold platings are suitable for
volume and prototype applications
where the added cost of crimp tools is
not justified.
improved precision and durability. They
applications with 50 or fewer mating
are recommended for applications with
cycles. Thicker gold platings are recom-
more than 200 mating cycles.
mended for more than 50 mating cycles.
High Conductivity: These contacts
use a different base material then the
standard contacts. They are recommend-
ed for high current applications. These
contacts will also reduce the derating of
connectors with several high current lines.
Stamped versus Machined: The two
part stamped contacts are manufactured
to precise tolerances and are field proven.
They can be supplied on reels which
lowers assembly costs for volume
Crimp versus Solder: Crimp contacts
offer improved electrical performance,
strain relief and quality control compared
to solder cup contacts. Solder cups
contacts are recommended for low
