TESTING BY TRIAXIAL METHOD
The TV and CTV Series III connector with standard
solid metal to metal coupling, EMI grounding fingers
and conductive finishes has proven to be the ultimate
in EMI/EMP shielding effectiveness. The charts il-
lustrate shielding effectiveness data which is typical
of Tri-Start connectors tested with the nickel finish
(Class F-metal, Class M-composite) over a wide fre-
quency range.

The vibration capability of the Tri-Start Series is
shown in the chart below. This illustrates the most
severe vibration envelope of any qualified connec-
tor available today.
These capabilities along with a 200°C temperature
rating and superior moisture sealing protection pro-
vide the user with a connector that can withstand
the most rigorous application.
