TEMPERATURE LIFE W/CONTACT
LOADING
Wired mated condition, with contacts under specific load: #220 (5 lbs.);
#16 12.5 lbs. A current of 100 MA was applied during life of test. Test
duration, 1000 hours at temperature of + 200˚C (392˚F).
Withstand temp life. No damage. No
discontinuity higher than 1.0 microsecond. No
contact dislodging order load.
No evidence of contact dislodging and/or electrical disconinuity of 1.0
miscrosecond or greater during the speified temperature life exposure
under contact loading conditions. All post test requirements were met.
Conclusion
All subject test specimens, connector components,
materials, accessories and contacts covered by this
report satisfied and/or exceeded the specified
requirement.
The successful completion of the qualification pro-
gram as reported herein, demonstrates the capa-
bilities of the subject ITT Cannon DPK series
connectors to comply with stringent verification
qualification requirements in accordance with
MIL-C-83733. On the basis of testing, the DPK
connector series was granted full OPl status to
MIL-C-83733.
