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
Finishes A, B and C withstand 500-hour salt spray.
Finish F withstands 48-hour salt spray.
Mated connectors withstand a minimum of 250 mating
cycles for RFI plug (MS27484) and 500 cycles for MS27473
and MS27500 plugs.
Wired, mated connectors with specified accessories
attached, shall meet the altitude-immersion test specified by
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.
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.
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
- 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:
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,
Mated connectors withstand the following vibration levels:
- Random vibration per MIL-STD-1344, method 205 test
condition VI, Letter “J”.
