MIL-C-83733
DPK
Test Data
The following is a presentation of the certified
capabilities of Cannon's DPK, high performance,
rectangular, rack and panel series connectors with
respect to critical qualification performance and
design requirements of MIL-C-83733. The data
presented herein is a condensation of authentic
qualification test data extracted from the original
qualification reports on file at the ITT Cannon Test
Laboratory.
The successful completion of the conducted qual-
ification program clearly demonstrates the compli-
ance of ITT Cannon, DPK series connectors and
contacts to meet or exceed the performance re-
quirements of MIL-C-83733.
