General Information
The MARC 53 Series
Connector family represents
a major advancement in the
design of high density (.080
[2.03] contact centers), sub-
miniature, power and coaxi-
al contact connectors. The
MARC 53 Series Connectors
consists of two connector
styles — the Military
approved MD53 featuring
shoulder entrapped con-
tacts, and the new RMD53
utilizing rear insertable/
removable contacts.
MARC 53 Series Connectors
combine positive lock —
the rugged, push-pull, lock-
coupling mechanism — with
the unique positive seal
multiple sealing system.
Positive lock is our new fin-
ger-tip, push-pull coupling
with the safety lock feature,
and is the only connector
made with positive “blind
mating” indication. When the
plug is fully engaged, the
coupling ring can be rotated
45° to the safety lock
position; if the plug is not
Materials and Finishes
Housings and quick discon-
nect couplings are machined
from bar stock aluminum to
combine maximum strength
with minimum weight.
Threaded couplings are
machined from non-mag-
netic, stainless steel bar
stock for durability of the
coupling threads. Contacts
are manufactured from high
conductivity copper alloys
which have been selected

completely engaged, the
coupling ring cannot be
turned to the safety lock
position. Consequently,
under “blindmating” condi-
tions, it is always possible
to determine if the plug is
properly engaged without
visual reference, damage, or
accidental disengagement.
The environmental integrity
is guaranteed by multiple
seal construction using sili-
cone rubber “0” rings and a
floating, voidless insert con-
struction. The floating insert
design allows the inserts to
move within the connector
housing to control interfacial
sealing pressure in spite of
tolerance accumulation, and
a compression interfacial
seal with minimum engaging
force. Both the primary “0”
ring system and the contin-
uous dielectric construction
withstand the MIL-C-38300A
altitude breathing test. The
sealing system meets the
air leakage requirements of
not more than 1 cubic inch
for low contact resistance
over the operating range of
the connectors. Inserts are
molded from flame-resistant,
glass-filled diallyl phthalate,
meeting ASTM D5948
requirements. All resilient
parts are made of high-
temperature, silicone
elastomers. Fuel resistant
compounds are used

redundant sealing method
is indicative of the inherent
reliability built into our
connectors.

power contacts are manu-
factured from high grade
copper alloys, and are
designed to be crimped
with standard M22520
tooling using subminiature
contact locators.
MARC 53 Series Connectors
incorporate hard insulators
in both the plug and recep-
tacle inserts for exceptional
contact stability. Shoulder
entrapment positively
retains the front insertable
MD53 contacts between
the front and rear insulators.
The new RMD53 contacts
are rear insertable and
removable and are retained
within the connector insula-
tors by clips which can be
visually inspected. No inser-
tion or extraction tools are
connector. All materials are
selected for their non-
magnetic properties.
The standard finish is hard
black, non-conductive,
anodized finish on connector
housings and quick discon-
nect couplings; stainless
steel threaded coupling is
passivated with black oxide
finish. Conductive finish

are truly field serviceable…
no special tools are required
for maintainability. In addi-
tion, connector subcompo-
nents damaged through
handling or misuse can
be procured separately
generally without the need
to scrap entire connector
units.
Weight reductions as high
as 67% are achieved with-
out loss of performance.

are available in both environ-
mental and hermetic styles.
In addition to the positive

pling plug is also available.
