(bright) cadmium over electroless nickel

Corrosion Resistance
Finishes A and B withstand 500-hour salt spray.
Finish F withstands 48-hour salt spray.

Durability
Minimum of 500 mating cycles

Environmental Seal
Wired, mated connectors with specified accessories
attached, shall meet the altitude-immersion test specified in
MIL-DTL-38999.

Fluid Resistance
Connectors resist specified immersions in MIL-PRF-7808,
MIL-PRF-23699, MIL-PRF-5606, M2-V Chevron oil, Coolanol
25, MIL-DTL-83133 (JP-8), MIL-DTL-5624 (JP-4, JP-5),
SAE-AMS1424 Type I, and other solvents and cleaning agents.

Shell-to-Shell Conductivity

  • Finish F = 1.0 millivolt maximum potential drop
  • Finishes A and B = 2.5 millivolts maximum potential drop

Shielding Effectiveness
RFI and EMI attenuation at the specified frequencies meet
the requirements of MIL-DTL-38999.

  • 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.

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 ± 15 percent magnitude with duration of
3 ± 1 milliseconds applied in three axes per MIL-STD-1344,
method 2004.

High Impact Shock
When mounted as specified in MIL-S-901, grade A, a drop
of a 400 lb. Hammer from 1 foot, 3 feet and 5 feet applied to
connector in three axes, totaling nine impacts.

Vibration
Mated connectors, with proper accessories, withstand the
following vibration levels:

  • Sine Vibration per MIL-STD-202, method 204, test
    condition G.
  • l Random Vibration per MIL-STD-1344, method 205, test
    condition V and test condition VI, Letter “J” at ambient
    temperature.
