Characteristics (Continued)
Maximum Current—Maximum cur-
rent rating of Commercial MATE-N-LOK
connectors is limited by the maximum
operating temperature of the housings
which is 105°C including the tempera-
ture rise of the contacts which is a
maximum of 30°C. There are several
variables which have a direct effect on
this maximum current-carrying capabil-
ity for a given connector and must
be considered for each application.
These variables are:
Wire Size—Larger diameter wire will
carry more current since it has less
internal resistance to current flow and
thus generates less heat. Longer wire
lengths also enhance current-carrying
capabilities since the wire conducts heat
away from the connector.
Connector Size—In general, the more
circuits in a connector, the less current
can be carried.
Ambient Temperature—The higher
the ambient temperature, the less current
can be carried in any given connector.
Printed Wiring Board Conductor
Size—The finished trace conductor
width and thickness should be maxi-
mized to allow for the greatest current-
carrying capacity and heat dissipation.
Commercial MATE-N-LOK connectors
also will withstand the following tests:
Vibration—10-55-10 cycles per
minute at .06 inch total excursion
Physical Shock—18 drops,
50 G sawtooth at 11 milliseconds
Housing Panel Mount Retention—
40 lb. min. 3 and 4 circuit
65 lb. min. 6, 9, 12, and 15 circuit
Housing Lock Strength with
Positive Locking Devices
Engaged—
25 lb. min.
Thermal Shock— -55°C to +85°C
Temperature-Humidity Cycling—
25°C to 65°C at 95 RH
Corrosion—48 hr. at 5% salt
concentration

Wire-to-Board
Due to the vast differences in trace
geometry and printed circuit board
configurations, we are unable to
provide a separate current carrying
chart for our printed circuit board
header products. However, the
above Wire-to-Wire charts may be
used as a guideline for headers if
the trace width and thickness is
equal to the listed wire gauge. For
vertical headers, only 95% of the
Wire-to-Wire value should be used.
For right-angle headers, only 75% of
the Wire-to-Wire value should be
used. The chart values are only a
tool for connector selection and will
require the customer to fully test
their application.

Note: If wire lengths used are less than those listed above, the current carry-
ing ability of the system will be reduced due to less heat being conducted
away from the connector. The customer should fully test all applications.
