ASSEMBLY TORQUE VALUES
Amphenol recommends the following torque values
for its adapters while assembling them to the
connectors. These values are based on the coupling
thread strength specified in SAE-AS85049 standard.

STYLE-2 CONFIGURATION
Some design consideration will require bigger diameter cable
to be terminated in the smaller shell size connectors. Cable
with heavy/thicker shielding, many wires for different branches/
routing are some of the examples. Such cable termination will
require a bigger adapter body with cable entry dimensions more
than the connector rear side dimensions Amphenol also sup-
ports this kind of application. The coupling end of the adapter
will be modified to Style-2 design as shown in the figure below
in such cases. The overall length of the Style-2 design adapters
would be increased by approx. 1 inch (25.mm) as shown. This
alternative design is applicable for all the Backshell Families
listed in this catalog.
