How to read this profile

Interface identification and source-scoped construction only. No measured drawing, mirrored rear view, termination map or electrical pinout is supplied.

Source-scoped identification facts

Each value retains its exact example, role and measurement axis. Facts from different parts must not be combined into an invented component.

Recorded variant and source limits
  • No universal contact count, numbering, mating dimensions, clearances or tolerances are published here.
  • The brief is undated; do not apply its frequency row to every product, variant or current revision.
  • Retained pitch context (excluded from normalized contact/body field): 15.5 mm / Source-described pitch / centerline. Panel-density examples only: not mating diameters, contact pitch, tolerances, minimum clearances or fabrication dimensions. Sources: S424: Page 1: interface-density illustration and BNC/Mini-BNC/HD-BNC electrical specification columns.
