MIL-C-5015 Connectors MS-E/F/R/ER
How to Order
ITT Cannon is the foremost manufacturer of MS and
MS type connectors with the widest range of
connector styles, sizes and variations in the indus-
try. These connectors utilize the finest materials,
which, along with precision manufacturing and rigid
quality control, assure ITT Cannon customers of the
finest quality connectors.
These circular 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.
ENVIRONMENTAL RESISTANT MS-E, MS-F,
MS-R AND F80 (Solder/Crimp Termination)
MS-E, MS-F and MS-R are similar to MS-A and
MS-B connectors but have resilient insulators and
wire sealing grommets for extreme environmental
conditions and high altitude sealing. MS-E's and
MS-F's have a mechanical cable clamp; the MS-R
has a shorter, lighter weight endbell without the
cable clamp. Both the MS-F and MS-R have 0 rings
to supplement the interfacial seal. Shells are alumi-
num alloy. Contacts are siliver plated copper alloy.
The F80 modification (crimp contact termination) is
available in E, R, F and BFR styles with resilient
insulators.
In the latest revision of MIL-C-5015, a new class of
environment-resistant connectors was added. This
new class F connector supersedes the previous
class E connector. The MS3106F is identical to the
MS3106E except that the MS3106F has an "0"
ring under the coupling nut. The class E will still be
available upon request for exitsting programs, and
upon ordering will also bear the E nomenclature on
the shell.
MS-F and MS-R connectors are designed to operate
in the extreme environmental conditions of high
altitude filight and must be completely sealed to
withstand moisture, condensation, vibration, corona
and flashover caused by high altitude environments.
They have resilient grommet with internal restric-
tions in the wire cavities which act as 0 rings
around the wires. This allows the wires to slide thru
the grommet with a minimum of friction, yet when
the ferrule is seated and the endbell tightened it
provides a perfect wire seal thru a wide variety of
wire diameters. This seal at the rear, plus the
interfacial seal at the front, effects a completely
environment-resistant asssembly when the plug is
mated to and F or R receptacle. Sockets are of the
closed-entry type.
The temperature range for this connector is -55˚C
(-67˚F) to +125˚C (+257˚F) and meets the
requirements of MIL-C-5015.
The F80 modification (crimp contact termination) is
avialable in resilient insulators in the E, R, F, and
BFR styles, creating a large selection of insert
assemblies and hardware. Components are identical
to the MS-5015 except that the contacts are
modified for crimp termination providing and in-
expensive crimp contact connector with the proven
reliability of and complete intermateability with the
MS-5015 series. See page 187 for assembly in-
structions. Cable clamps have been integrally de-
signed with the endbell on MS-E and MS-F connec-
tors. Class R is without the cable clamp.
POTTING ER CONNECTORS (Solder Contact
Termination)
These lightweight potting connectors provide re-
sistance to salt water, fuels, etc., and will with-
stand the effects of high vibration. 3100 and 3106
connectors with plastic potting cups and resilient
inserts meet the requirements of MS3103 and
MS25183. Contacts are silver plated copper or
brass. ER insulators are resilient; shells are alumi-
num alloy. A 90˚ plug (3108ER) is also available.
ACCESSORIES
Accessories to fit MS connectors include junction
shells, protective caps, dummy or stowage recepta-
cles, cable clamps, telescoping bushings.
