MS-R
Specification requirements for greater reliability in a
shorter, lighter weight environmental resistant connector
led to the design of the MS-R. MS Class R connectors
satisfy all the performance requirements of MIL-DTL-
5015.
This low profile assembly was attained by moving the
axial compression nut and grommet assembly forward
and flush with the rear of the insert. The neoprene grom-
met, with its low coefficient of friction, assures easier
threading of wire bundles and quicker assembly and ser-
viceability of the unit. Molded webs in each wire hole
insure a moisture barrier around each wire.
The addition of an “O” ring at the main joint of all
MS3106R plugs provide a main joint seal supplementary
to the interfacial seal, thus insuring a higher degree of
reliability when connector halves from different sources
are employed. MS-R types are recommended for new
design applications.
Shells:
Shell components are fabricated from high grade alumi-
num alloy. All components have the standard electrically
conductive cadmium plated finish with an olive drab chro-
mate after-treatment for corrosion resistance. Consult
Amphenol, Sidney, NY for other plating options.
Contacts:
Contacts are machined from copper alloy for maximum
corrosion resistance, maximum current carrying capacity
and low millivolt drop. Both crimp and solder versions are
available. Refer to pages 49, 67 and 68 for additional
contact information.
Inserts:
Resilient neoprene inserts provide an outstanding mois-
ture barrier, maximum vibration resistance and high
dielectric strength. Either pin or socket insert can be
pressurized.
