Dielectric Withstanding Voltage

Current leakage less than 2 milliamps at 1500 VAC

Insulation Resistance:

1000 megohms minimum at 250 C.

Current Rating (Contact current rating @ 1250 C (continuous)

Size 20: 7.5 amps

Size 16: 13 amps

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.

Temperature:

Operative at temperatures from -550C to +1250C. Continuous at rated

current.
