Operating Area
The thermal properties of the materials used in the
construction of a connector limit the current carrying
capacity. There are a number of factors that determine the
amount of current that can be handled: contact spacing,
size of cable, ambient temperature and the heat that is
generated by the current passing through
the connector.
The maximum current varies with dierent contact layouts,
and because of these factors it is necessary to produce
de-rating curves for each pole variant. This de-rating curve
is specied in the standard IEC 60512 part 3. De-rating
curves are plotted for each contact carrier combination
with the current being carried simultaneously by all
contacts. These graphs show the heat rise generated
as the current is increased.
The red line indicates the direct correlation between current
applied and the measured temperature rise within the
connector. The dotted blue line shows rated current and
the green line is derived by applying a factor of 0.8 to the
original plot data to give a de-rating curve. The dashed
blue line shows the rated current.
The shaded area under the 0.8 curve shows the permitted
operating area, and allows safe current vs ambient
temperature characteristics to be determined.
