ing to meet your production
requirement.
The contacts present in this
catalog were specifically
designed for AMP M Series,
CPC (Circular Plastic
Connectors), Circular
Metal-Shell, Metrimate
(True Metric Dimensions),
and “G” Series connectors.
How to choose the
correct connector/contact
combination.
Choosing the correct con-
nector/contact combination
is essential to the proper
function of any AMP con-
nector. A customer must
first evaluate each individ-
ual application with regards
to wire size(s), number of
circuits, available space,
and fastening method. The
customer must then con-
sider the following factors
to make the right selection
of connector/contact/
hardware:
a. Connector Type. This
decision is based on the
selected contact types,
coupling method, circuit
density requirements
and, if posted connec-
tors are desired, in-plant
production capabilities of
wiring connectors using
hand tools or semiauto-
matic tooling.
b. Contact Type. This deci-
sion is based on wire
size(s) and the reliability
and cost requirements of
an application, as well as
the customer’s in-plant
production capabilities.
c. Hardware Selection. This
decision is based on the
connector type, and the
application requirements
for fastening, protection,
shielding, guiding, strain
relief and keying.

these connectors and associ-
ated hardware, refer to the

Current Carrying Capabilities
Current Carrying Capabilities
The total current capacity of
each contact in a given connec-
tor is dependent upon the heat
rise resulting from the combina-
tion of electrical loads of the
contacts in the connector
arrangement and the maximum
ambient temperature in which
the connector will be operating.
Caution must be taken to ensure
that this combination of condi-
tions 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 deter-
mining this maximum current
capability for your application
are:
s
Wire Size
—Larger wire will
carry more current since
it has less internal resistance
to current flow and generates
less heat. The wire also con-
ducts heat away from the con-
nector.
s
Connector Size
—In general,
with more circuits in a connec-
tor, less current per contact
can be carried.
s
Current Load Distribution
—
Spreading those lines with
greater current loads through-
out the connector, particularly
around the outer perimeter,
will enhance heat dissipation.
s
Ambient Temperature
—With
higher ambient temperatures,
less current can be carried.

Practical current-carrying capac-
ity is not an absolute, but an
application-dependent condition.
New Method Simplifies Ratings
To help the designer set the
appropriate current level, Tyco
Electronics has developed a
method of specifying current-
carrying capacity. This method
takes into account the various
application factors that influence
current rating.
The method can be summarized
as follows:
s
s
Current Rating Verification
Can a contact rated at 10
amperes carry 10 amperes?
Maybe yes, but probably not.
The reason lies in the test condi-
tions used to rate the contact. If
these conditions do not ade-
quately reflect the application
conditions, the actual allowable
current levels may be lower than
specified levels. For example,
many manufacturers, including
Tyco, test a single contact in air.
This gives an accurate measure
of the basic current-carrying
capacity of the contact. Use the
contact alone in air and it can
certainly carry 10 amperes. Use
it in a multi-position connector
surrounded by other current-
carrying contacts or in high
ambient temperatures, and
the contact should carry less
current.
Similarly, as the contact ages
and stress relaxation, environ-
mental cycling, and other degra-
dation factors take their toll, the
contact’s current-carrying
capacity decreases. A prudent
design must set current levels
for such end-of-design-life
(EODL) conditions.
s
s
The contact is aged to EODL
conditions by durability
cycling, thermal cycling, and
environmental exposure.
The contact’s resistance sta-
bility is verified.
The current necessary to pro-
duce the specified tempera-
ture rise is measured. This
T-rise is usually 30°C.
A rating factor is determined
to allow derating of multiple
contacts in the same housing
and for different conductor
sizes.
as well by convection, the maxi-
mum T-rise will be realized at a
lower current level. Conse-
quently, the allowable current
level must be lower to maintain
an acceptable T-rise.
For a given connector, the cur-
rent level will be set by the load-
ing density. A connector
containing 50% current-carrying
contacts will permit higher cur-
rents (per contact) than a con-
nector will at 75% loading. The
loading percentage assumes an
even distribution of contacts
within the housing. If all 10 con-
tacts are grouped together in
one section of a 20-position con-
nector, the loading density may
approach 100%.
of tests that exercises the major
failure mechanisms and thereby
simulates EODL conditions.
Conditioning includes mating
cycling, industrial mixed-flowing
gases, humidity and tempera-
ture cycling, and vibration to
sequentially introduce wear, cor-
rosion, stress relaxation, and
mechanical disturbance.
Presentation
The presentation of current-
carrying capacity in AMP
product specifications includes
two parts:
s
First, a base curve showing
current levels versus T-rise for
a single circuit and the largest
wire size. This represents the
maximum current capacity of
the contact. The curve is usu-
ally flat up to 75°C ambient
and then drops off. Up to
75°C, the 30°C T-rise limits the
amount of current, and above
75°C the current must be
reduced to keep the combina-
tion of ambient temperature
and T-rise from exceeding the
maximum operating tempera-
ture of 105°C.
The Importance of EODL
As stated, T-rise in a contact
depends on both resistance and
current. As it ages, a contact’s
resistance will increase. The
contact designer will specify a
maximum resistance for the con-
tact, this level is the end-of-
design-life resistance. Before the
contact is tested for current,
Tyco subjects it to a sequence
Temperature
One other factor influencing cur-
rent levels is the maximum oper-
ating temperature, for example,
105°C. If the application has a
high ambient temperature (over
75°C) the contact’s T-rise is
limited by the maximum operat-
ing temperature. For example,
an application temperature of
90°C limits the contact T-rise to
15°C. Since current produces
heat (the I
2
R law), the current
must be lowered to limit the
T-rise.
A contact’s T-rise depends not
only on its I
2
R Joule heating, but
also on its ability to dissipate the
heat. Consider a contact in a
multi-contact housing. Joule
heating in multiple contacts will
raise the local ambient tempera-
ture. Since the contact will not
be able to dissipate its own heat
Figure 1
Graph shows the relationship between base current, ambient tempera-
ture, and contact T-rise.

Current Carrying Capabilities

(Continued)
Next are rating factors, a table
of multipliers to account for
connector loading and for
smaller wire sizes. The
designer first determines the
base current for the ambient
conditions of the application;
then multiplies this base cur-
rent by the rating factors to
find the current level for the
application’s loading factor
and wire size.
An Example:
To demonstrate the method of
specifying current, consider the
following application conditions;
an ambient temperature of
65°C, a 50% loading of con-
tacts in the housing, and
20 AWG [0.6mm
2
] wire.
s
From Figure 1, the base cur-
rent rating is 14 ampere with
18 AWG [0.8mm
2
] wire.
s
Figure 2, the rating factor for
50% loading and 20 AWG
[0.6mm
2
] wire is 0.68.
s
The specific rating for this
application is the product of
the base rating and the rating
factor:
14 x 0.68 = 9.5 ampere
s
Each of the contacts can
carry 9.5 ampere.
s
However, if the ambient tem-
perature is 80°C the allow-
able T-rise becomes 25°C.
The base current must be
lowered to 12.8 ampere so
that the 105°C maximum
operating temperature is not
exceeded. The current rating
then becomes:
12.8 x 0.68 = 8.7 ampere.
Practical Values
The current-rating method
gives designers practical val-
ues applicable to their applica-
tions. While the specified
current levels for a contact may
be lower than for other testing
methods, they are more realis-
tic and simplify the system
design process.
“Spec-manship” is replaced by
a realistic assessment of the
current-carrying capacity of a
contact under varying condi-
tions of temperature, connector
loading, and wire size.
Figure 2
Rating factors allow the base current to be adjusted for various connec-
tor loading and wire sizes.

Precision formed pin and socket contacts in Size 16. They
are used in M Series, Special M Series, “G” Series,
Metrimate, Metrimate Drawer, and CPC Series 1 and 4
connectors. Contacts feature a high normal force which
provides a low resistance in significant applications such
as dry circuit signal conditions. Mating entry is closed-
ended to prevent damage from stubbing due to misalign-
ment. Stainless steel spring provides superior normal force
and retention in the housing. Tyco Electronics proprietary
gold plating process is designed so that specified plating
thicknesses are controlled on the inside of the socket,
which is the critical contact mating area. The contacts are
formed from brass. Single contact rating is 13 amperes at
30°C T-Rise.
See page 9 for product details.
Type III+, Solder Type, Size 16
As with the crimp snap-in Type III+, these precision formed
solder-type contacts are also used in M Series, Special
M Series, Metrimate, Metrimate Drawer, and CPC Series
1 and 4 connectors. Contacts feature a high normal force
which provides a low resistance in significant applications,
such as dry circuit conditions. A preformed wire barrel
accepts both stranded and solid wire, while the preformed
insulation barrel provides strain relief for various wire insu-
lation thicknesses. Mating entry is closed-ended to prevent
damage from stubbing due to misalignment. A stainless
steel spring provides superior normal force and retention
in the housing. Tyco Electronics proprietary gold plating
process is designed so that specified plating thicknesses
are controlled on the inside of the socket, which is the criti-
cal contact area. Single contact current rating is
13 amperes at 30°C Temperature Rise.
See page 10 for product details.
Type III+, Solder Tab, Size 16
A companion contact style to the crimp snap-in and solder-
type, the Type III+ Solder Tab is compatible with the same
AMP connector families, and features high normal forces to
provide a low resistance in significant applications. A pre-
crimped solder tab with slot accepts various sizes of solid
and stranded wire. Mating entry is closed-ended to prevent
stubbing due to misalignment. A stainless steel spring pro-
vides superior normal force and retention in the housing.
