Corrosion Resistant
Class C, W, Y, will withstand 500 hours salt spray.
Class F, N, will withstand 48 hours salt spray.
Fluid Immersion
Connectors are fluid resistant to many fuels, solvents, coolants and oils.
High Impact Shock
Mated conectors terminated with MIL-C-915 cable and environmentally sealed backshells will
withstand high impact shock per MIL-S-901. Applicable to Series I & III only.
Altitude
Other Environments
