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.
Temperature:
Operative at temperatures from -55
