50 Ohm BNC Plug for Cable-Terminated RF Paths
The 000-46650-51RFX: Gold plating on the contact and nickel on the body keep the mating interface corrosion-resistant and the shield continuous across the connection.
50 Ohm Impedance — the Signal Path Standard
The 50 Ohm characteristic ensures the connector does not introduce a reflection at the junction.
Free-Hanging Cap Termination — Cable Assembly Fit
The free-hanging, cap-style mounting means this plug terminates the end of a cable, not a panel or PCB. The cap body accepts the prepared cable end and is crimped or clamped per the manufacturer's assembly instructions — the exact cable diameter range and crimp tool are specified in the Amphenol RF application note for this series.
Gold Contact, Nickel Body — Surface Finish Choices
Gold on the male pin and nickel on the shell are the standard finishes for a BNC plug that sees repeated mate-unmate cycles in a lab or field environment. Gold resists oxidation on the signal path; nickel keeps the outer conductor ground path low-resistance and the connector body from corroding in humid or outdoor cabinets. The contact finish is gold, not tin or silver — tin would gall under repeated mating, and silver tarnishes in sulphur-rich air.
