DL/DLM/DLD Temperature/Current Rating

The ambient temperature curves shown represent

the rated current carrying capacity of the Cannon

DL1/2/3/4, DLM1/2/3 and DLD1/2 electrical

connectors, derated to 80% of the values recorded

using the methods specified by International

Electro-Technical Commission Document 48

(1975).

Current was applied to the total connector (all

contacts) in one-half ampere increments and

maintained at each current level until thermal

stability was achieved. A thermocouple inserted

into the ‘‘hottest area’’ of each connector then

measured the connector temperature at the same

time that an ambient temperature reading was

taken. The difference between the two measured

values is the heat rise or self-heating created solely

by the current flow, and this temperature rise for

the current level was deducted from the insulator

material rated temperature. These values were

then derated to 80% to obtain the curves shown.
