FIELD REFERENCE / COMPACT COAXIAL
Small bodies.
Specific identities.
SMB, Mini-BNC, DIN 1.0/2.3 and RP-TNC. Separate the coupling, the component role and the electrical requirements before deciding what connects.
01 / IDENTITY
Which component?
Two studies identify exact ordered parts. One preserves its named-family scope. Similar appearance is not a substitute for identity.
02 / ROLE
What is attached?
A board jack, a cable-end body and a bulkhead jack have different jobs. Keep component and termination roles beside the image.
03 / EVIDENCE
What remains unknown?
Typical family specifications and an unnumbered photograph do not establish exact impedance, performance or complete-path compatibility.

Inspect view & provenance (private workspace)Mini-BNC, DIN 1.0/2.3 and RP-TNC gain their first registered specimens. These original qualitative studies are not at a common scale. The DIN source photograph does not select an order code or impedance. Loose contacts visible in manufacturer sources are not silently installed in the studies. Existing lead illustrations stay unchanged.
