Submersion:
Properly wired and mated connection will withstand immersion under
three feet of water without loss of electronic qualities or leakage.
Fluid Resistance:
Connectors show no damage when exposed to most fluids used in
industrial applications.
Vibration:
No unlocking or unmating and exhibits no mechanical or physical
damage after sinusoidal vibration levels of 20 G’s at 10 to 2000
Hz in each of the three mutually perpendicular planes. No electrical
discontinuities longer than 1 microsecond.
