Material Specifications
Contacts
The material composition
and construction of AMP
Type III+ contacts encompasses
varying price
ranges and performance
characteristics. Specific
materials and available plating
thicknesses of each
contact are provided.
Housings
M Series V.35 connector
housings are made of
general purpose phenolic
(black) or polyester (black).
Phenolic housings are
molded of material per
MIL-M-14, Type CFG. The
performance characteristics
of this material makes the
connector an excellent
choice in applications where
exceptional resistance to
acids, alkalies, or solvents
is not a prime factor.
Hardware
A variety of materials such
as plated steel, stainless
steel, zinc (nickel plated)
and aluminum are used in
the manufacture of M Series
V.35 connector hardware.
This provides for the proper
operation and durability of
each hardware component,
while offering a choice of
economies to satisfy particular
application requirements.
Dimensions are in inches and millimeters
unless otherwise specified.
Values in brackets are metric equivalents.
Current Carrying Capabilities
The total current capacity
of each contact in any given
M Series connector is
dependent upon the heat
rise resulting from the combination
of electrical loads
of all contacts in the connector
arrangement and the
maximum ambient temperature
in which the connector
will be operating. Caution
must be taken to insure that
this combination of conditions
does not cause the internal
temperature of the connector
to exceed the maximum
operating temperature
of the housing material.
Several variables which
must be considered when
determining this maximum
current capability for your
application are:
a) Wire Size - Larger wire
will carry more current
since it has less internal
resistance to current flow
and generates less heat.
The wire also conducts
heat away from the
connector.
b) Connector Size - In
general, with more
circuits in a connector,
less current per contact
can be carried.
c) Current Load Distribution -
Spreading those lines
with greater current loads
throughout the connector,
particularly around
the outer perimeter, will
enhance heat dissipation.
d) Ambient Temperature -
With higher ambient
temperature, less
current can be carried.
