4.0 RATINGS
4.1 SAFETY AGENCY RATINGS
(Current ratings are maximum and may vary depending on wire size, circuit count, and end-use
application. Further testing may be required in the end-use application.)
4.2 CURRENT DERATING AND APPLICABLE WIRES
Current is dependent on connector size, contact material, plating, ambient temperature, printed
circuit board characteristics and related factors. Actual current rating is application dependent
and should be evaluated for each application.

The “T” dimension defines a “free” length of wire, or a length of wire that is not subject to significant
bias by external factors such as a wire tie, wire twisting, or other means of bending or deforming of the
wires that repositions them from their natural relaxed state or location where they enter the housing.
Wires are to be dressed in such a manner to allow the terminals to float freely in the pocket.

8.5 MATING VELOCITY
Blind Mate Interface connectors should not be mated together at excessive velocities.
Depending on the specifics of the application, excessive mating speeds may not allow
sufficient reaction time for the connectors to properly self align and this can cause
damage to connector housings and terminals. Molex recommends mating speeds do
not exceed 40 mm/sec (1.6 inch/sec) for proper mating.
