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.
| Mounting | through-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. |
|---|---|
| Coupling / latch | Quarter-turn bayonetS208Named source examples retain separate role, part, view and axis limits; values are not a universal family specification. 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. |

Unknown fields stay unknown; illustrations supply no measurements or pin assignments.
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.
