The useful distinction
Recognize it. Then verify it.
The cited LEMO implementation uses one triax contact system with a documented nominal impedance of 75 ohms. [C313A]
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
- Triax family and nominal impedance do not establish camera/CCU or instrumentation standard, cable construction, conductor roles, signal direction or complete system compatibility.
- Product-specific dimensions and mating examples do not constitute a fabrication drawing, universal interchangeability result or cable-assembly approval.
Bounded facts, visible unknowns
Specifications and limits
| Documented identification | LEMO identifies the cited product as one triax contact system with 75-ohm impedance. [C313A] |
|---|---|
| Mechanical dimensions | No independently reviewed mechanical drawing in V50; do not use this page for fabrication, fit testing or tolerance work. |
| Engineering pinout | Source-checked engineering profile available; independent review pending. Open engineering profile → |
| Verified device list | Not included. Check exact device and accessory documentation. |
Use only the source-backed family, role or position count for identification. Resolve electrical ratings, protocol generation, lane wiring, signal assignment, cable construction and exact device support from the relevant equipment and component documentation.
Before you connect
What to check
- Identify the exact connector family and variant from the equipment or component documentation.
- Keep physical form, contact count, protocol, electrical rating and device support as separate facts.
- Do not force, rewire, adapt or install from this recognition record; resolve the remaining requirements first.
What is not established
This field note does not approve a connection, adapter, cable assembly, rewiring scheme, energized-work procedure or fabricated part. It intentionally omits unsupported pin assignments and mechanical tolerances.
