MS-E/F/R/ER
MIL-C-5015 Connectors
ITT Cannon is the foremost manufacturer of MS and
MS type connectors with the widest range of connec-
tor styles, sizes and variations in the industry. These
connectors utilize the finest materials, which, along
with precision manufacturing and rigid quality con-
trol, assure ITT Cannon customers of the finest qual-
ity connectors.
These circular connectors were originally designed
for aircraft, but are now widely used in many other
fields. They are particularly suitable for commercial
POTTING ER CONNEC-
TORS (Solder Contact
Termination)
These Lightweight pot-
ting connectors provide
resistance 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 aluminum alloy.
A 90º plug (3108ER) is also available.

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 condi-
tions 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 O rings to sup-
plement the interfacial seal. Shells are aluminum
alloy. Contacts are silver plated copper alloy. The F80
modification (crimp contact termination) is available

How to Order
In the latest revision of MIL-C-5015, a new
class of environment-resistant connectors
was added. This new class F connector super-
sedes the previous class E connector. The
MS3106F has an O ring under the coupling
nut. The class E will be available upon request
for existing 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 condi-
tions of high altitude flight and must be com-
pletely sealed to withstand moisture, conden-
sation, vibration, corona and flashover
caused by high altitude environments. They
have resilient grommet with internal restric-
tions in the wire cavities which act as O 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 diame-
ters. This seal at the rear, plus the interfacial
seal at the front, effects a completely environ-
ment-resistant assembly when the plug is
mated to and F or R receptacle. Sockets are of
the closed-entry type.

E, R, F, and BFR styles, creating a large selec-
tion of insert assemblies and hardware.
Components are identical to the MS-5015
except that the contacts are modified for
crimp termination providing and inexpensive
crimp contact connector with the proven reli-
ability of and complete intermateability with
the MS-5015 series. Cable clamps have been
integrally designed with the endbell on MS-E
and MS-F connectors. Class R is without the
cable clamp.
