Introduction
This catalogue describes Cannon connectors
designed and manufactured to MIL-C-5015, the
military specification covering MS electrical
connectors. These connectors were originally
designed for aircraft, but are now widely used in
many other fields. They are particularly suitable
for commercial applications requiring low cost
and high reliability.
The design of connector classes MS-E, MS-F and
MS-R conforms to MIL-C-5015 D. The new class
F connectors supersede the previous class E
connectors. For new programs only class F
should be ordered.The coupling measurements
as well as the dimensions of class MS-E, -F and
-R are in accordance with the latest revision of
VG 0095342. Wall mount receptacle, box re-
ceptacle, cable connector and straight plug have
the same coupling dimensions. This allows
mating of the different classes of these connec-
tors.
The connectors of class E, F and R are designed
to operate in extreme environmental conditions.
These connectors are completely sealed to
withstand moisture, condensation, vibration and
flash-over. MS-F and MS-R connectors have a
resilient grommet around each wire. This allows
the wires to slide through the grommet with a
minimum of friction. Yet when the ferrule is
sealed and the endbells are tightened, it provides
perfect wire seal through a wide variety of wire
diameters. This seal at the rear plus the interfacial
seal at the front, effect a completely environmen-
tal resistant assembly when the plug is mated
to an F or R receptacle.
Different Classes
Connector classes MS 3106F, MS 3106R and
MS 3108R feature an O-ring under the coupling
nut. It is missing on connectors class MS 3106E
and MS 3108E.
To reduce size and weight, connector classes
MS 3100R, MS 3101R and MS 3106R have no
cable strain relief. The 90° angle plug MS 3106R
has no cable clamp and is suitable for hose
connection. Strain relief for this connector has
to be ordered separately (see page 23). More-
over, construction and materials used are identi-
cal for all connector classes.
Different Designations
Connectors with MS designation conform to
MIL-C-5015 in respect of dimensions and con-
tact arrangements.
Deviations from this specification, e. g. crimp
contacts, other shell or contact finishes, are
designated CA.

Electrical Data
Operating voltage and connector usage
When the connectors in this catalogue are used for voltages greater than 50 Volts and have touchable
conductive shell parts they must be used in accordance with the safety regulations DIN VDE Part 410;
IEC 60364-4-41. This regulation basically dictates that the power source should be turned off before
any mating and unmating of the connector, this regulation does not provide for protection against
electrical shock when mating and unmating the connectors in the live condition.

Service rating
MS connectors show no evidence of breakdown when the test voltage given below is applied between
the two closest contacts and between the shell and the contacts closest to the shell for a period of
one minute.
High potential test voltage is conducted in VG 95319 part 2 test no. 5.13 and VG 95210 part 31.
