MARC 43 Series Connectors
Materials and Finishes
MARC 43 Series Connector
housings and quick
disconnect couplings are
machined from bar stock
aluminum to combine maxi-
mum strength with minimum
weight. Threaded couplings
are machined from non-
magnetic, stainless steel
bar stock for durability of
the coupling threads.
Contacts are manufactured
from high conductivity
copper alloys which have
been selected for low
contact resistance over the
operating range of the
connectors. Inserts are
molded from flame-resist-
ant, glass-filled diallyl
phthalate, meeting ASTM
D5948 requirements. All
resilient parts are made of
high temperature, silicone
rubbers. Fuel resistant
compounds are used
where swelling affects the
performance of the
connector. All materials are
carefully selected for their
non-magnetic properties.
The standard finish is clear,
non-conductive anodize on
connector housings and
quick disconnect couplings.
For threaded coupling
applications, aluminum
components are hard, black
anodized, and stainless
steel plug coupling is
passivated with black oxide
finish. Conductive finish
modifications include gold,
cadmium, and iridite
finishes. Contacts are gold
plated per MIL-G-45204
requirements. See page 63
for modification information.
General Information
Service and Performance Data
A high density (.080 [2.03]
contact centers), lightweight,
subminiature, cylindrical
connector series featuring
crimp contacts and finger-
tip, push-pull, quick discon-
nect coupling. This series
conforms to the applicable
performance requirements
of MIL-C-26482 and is
available in unsealed,
environmentally sealed, and
hermetic types.
A large assortment in insert
arrangements — accommo-
dating AWG 12 through 32
gauge wire and miniature
coaxial cables — is available
for the design engineer’s
choice. The contacts are
retained by shoulder
entrapment and can be
crimped with the standard
M22520 tools, using appro-
priate locators.
This proven series of con-
nectors has a long history of
outstanding performance
on many military and aero-
space programs. MARC 43
Series Connectors are ideal
for applications where high
performance must be
achieved at low cost.

Smaller jacketed cable can be accommodated but environmental seal may
be impaired. Smooth extruded jacket should be used for consistent wire
