ELECTRICAL SERVICE DATA
High Voltage Cartridges for MS-E and MS-R (HV310*E/R Series)
For class E, R and F connectors, satisfactory mois-
ture sealing will be obtained if AWG and MS wire
sizes and insulation outside diameters are governed
by this table.
Test current ratings of contacts and allowable
voltage drop under test conditions when assembled
as in service are shown below. Maximum total
current to be carried per connector is the same as
the allowable in wire bundles as specified in MIL-
W-5088.

CONTACTS
Pin and socket contacts are designed to resist severe vibration and repeated connection and disconnection.
The average force to either engage or separate pin and socket contacts will not exceed the average values
given in the latest revision of MIL-C-5015.
THERMOCOUPLE CONTACTS
Sizes 12 and 16 contacts, machined from matching thermocouple lead wire alloys, can be supplied in
ITT Cannon connectors. These thermocouple contacs maintain continuity from thermal-sensor leads thru a
bulkhead of other closures in temperature measuring applications.
These contacts for matching lead wires are detailed by the standards of the Instrument Society of America
(I.S.A);
Since the thermocouple connector applications determines the soldering methods and materials to be used,
thermocouple contacts, identified by permanent markings, are normally supplied with untinned solder pots.
Thermocouple contacts are supplied only in connectors having resilient insulators.
HIGH POTENTIAL TEST VOLTAGE
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 voltage conductors as well as power and/or
control signal conductors can now be connected
simultaneously in standard MS connectors. Previ-
ously, MS connectors involved in high voltage cir-
cuitry required individual design considerations and
could only be ordered as a "special." The new high
voltage cartridge allows conversion of a standard
connectors to one capable of handling up to 15,000
volts DC (Test Voltage - mated), operating voltage
- See level 5,000 VDC or 3,500 VAC. These
cartridges are molded of nylon and provide as high
degree of arc-over protection between adjacent
contacts or between a contact and the connector
shell. Unmated, each cartridge provides a nylon
isolating barrier capable of withstanding up to
10,000 volts DC (or peak).

The contact within the cartridge is a 7.5 amp. size
20, crimp snap-in type with dielectric rear release
clip retention. This contact is removable with the
plastic CIET20 insertion/extraction tool provided
the insulation is .084 (22.45) or less. The contact
may be crimped with the standard MS-3191 tool
and MS-3191-20A locator and hand inserted into
the nylon cartridge. The cartridge body is installed
in the connector at the factory.
High voltage cartridges now available fit the space
normally occupied by a #4 o #8 size contact in an
MS-E, MS-R or MS-F type connector.
Over forty-nine contact arrangements are currently
available in which these high voltage cartridges may
be used. Contsult factory for ordering information.
