Performance Specifications

Operating Temperature Range
Finish B: -65°C to +175°C (-85°F to +347°F)
Finishes C and F: -65°C to +200°C (-85°F to +392°F)
Finish A: -65°C to +150°C (-85°F to 302°F)

Material and Plating Data (Finish)
B – aluminum shell, olive drab cadmium over nickel base
C – aluminum shell, black anodized finish
F – aluminum shell, electroless nickel finish
A – aluminum shell, silver to light iridescent yellow color
(bright) cadmium over electroless nickel base

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

Durability
Mated connectors withstand a minimum of 250 mating cycles for RFI plug (MS27484) and 500 cycles for MS27473 and MS27500 plugs.

Environmental Seal
Wired, mated connectors with specified accessories attached, shall meet the altitude-immersion test specified by 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
Maximum potential drop shall not exceed:

  • 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.

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 magnitude with duration of three milliseconds applied in three axes per MIL-STD-1344, method 2004.

Vibration
Mated connectors withstand the following vibration levels:

  • Random vibration per MIL-STD-1344, method 205 test
    condition VI, Letter “J”
