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.

Documented examples; not a mating drawing or compatibility approval
Mountingthrough-hole (Claim C205G)S540Recorded source-scoped values; named examples do not describe every family variant or establish compatibility. Printed p.5, exact row. A blank cell is unknown information, not an explicit no-mount statement.

Named series only, not every family part: Amphenol RF HD-BNC product family. Family coupling is useful identification context but is not automatically counted as a polarization/keying fact.; No part suffix, row/contact pitch, dimensional axis, physical marking or universal performance limit inferred.

Recorded variant and source limits
  • Full IEC 61169-70 and fabrication dimensions were not reviewed.
  • Exact part impedance, cable construction, frequency requirements and link performance need separate evidence.
