General Description
These electrical connectors are designated MS
because the interchangeability and operating
characteristics are determined by U.S. Military
Specifications. These specifications are revised
from time to time to incorporate performance
requirements dictated by design advances and
more stringent requirements of allied equipment.
The several designations of MS and 97B
connectors meet different requirements of MIL-
C-5015. These designations and general
descriptions are as follows :
Shell
Shell constructions include solid back shell (A)
and environmental resistant (E, F & R).
Environmental resistant connectors provide a
moisture barrier and assure a positive seal. Shell
styles consist of wall type receptacles (3100),
cable receptacles (3101), box receptacles
(3102), straight plugs (3106) and angle plugs
(3108). Shell hardware is manufactured from
aluminium alloy and cadmium plated with olive
drab chromate finish. This finish has excellent
conductivity; it is non-reflecting and corrosion
resistant. Black anodised finish and cadmium-
free zinc plating with olive drab chromate finish
are also available. For details, contact factory.
Contacts
Pin and socket contacts are of brass and
generally silver plated. Gold plating is also
available. For details contact factory. These
contacts are available for solder or crimp
termination. Special arrangements of contacts
for pre-mating and pre-earth are also available.
Inserts and grommet
Synthetic inserts and grommet manufactured
according to MIL-R-3065, offer high dielectric
strength and are resistant to oils, gasoline and low
temperature. DAP is dimensionally stable, has high
arc resistance and high insulation resistance under
both humidity and thermal stress.
General description
Plugs are available in A, F and R types. Receptacles
are available in A, E, F and R types.
A Solid back shell
Intended for general service usage to provide
convenient means of connecting and disconnecting
electrical circuits in industrial and military
applications.
Environmental resisting
Intended for use where the connector will be subject
to heavy condensation and rapid changes in
temperature or pressure and/or where the connector
is subjected to high vibratory conditions.
EEnvironmental resisting with grommet seal and
strain relief backshell except for 3102 type.
FEnvironmental resisting with grommet seal,
strain relief backshell and front gasket seal for plug
type.
REnvironmental resisting with grommet seal,
shorter and lightweight.
