C027Asource checked
BNC uses a bayonet coupling; both 50-ohm and 75-ohm variants exist.
E027 · No electrical assignment published
BNC connector engineering reference
Amphenol RF documents BNC as a bayonet-coupled family with 50-ohm and 75-ohm variants and MIL-STD-348 interface context. V54 does not normalize every variant into one contact map or performance ceiling.

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
- Exact 50-ohm versus 75-ohm variant and cable/system impedance must be resolved.
- Frequency range, return loss, cable construction and termination quality are not universal across BNC products.
