Not recorded: Nominal contacts, Positions / cavity span, Populated contacts, Contact rows, Contact pitch, Contact gender / arrangement, Coupling / latch, Keying / polarization, Shell / form, Recorded markings, View convention. Unknown fields stay unknown; illustrations supply no measurements or pin assignments.

Recorded variant and source limits
  • Mating length is not established for the generic record.
  • Polarity, voltage, current, connector tolerances and replacement approval remain unknown until the exact device and supply are documented.
  • Prior view context (not a source-view value): Cross-sectional identification schematic labels only outer and inner nominal diameters; no polarity is drawn.
