Shock and Vibration Requirements
Wired, mated connectors shall not be damaged, nor shall
there be a current interruption longer than one microsecond
when subjected to the following:
Standard Shock
Mated connectors withstand a pulse of approximate half
sine wave of 300 G magnitude with duration of three
milliseconds applied in three axes per MIL-STD-1344,
method 2004.
Vibration
Mated connectors withstand the following vibration levels:
G
exactly what peak voltages, switching currents, transients, etc.,
can be expected in a particular circuit.
With RFI spring fingers, finish F = 1.0 millivolt, while
finishes A and B = 2.5 millivolts.
Without spring fingers = 200 millivolts.
Finish C = nonconductive.
RFI shielding effectiveness of mated connectors with
RFI backshells is measured in a triaxial radio frequency
leakage fixture.
EMI shielding effectiveness is measured at the interface
of mated connectors and tested by the mode-stirred
technique specified in method 3008 of MIL-STD-1344.
Random vibration per MIL-STD-1344, method 205 test
condition VI, Letter “J”.
