Amphenol RF BNC Connectors & Adapters

Amphenol RF BNC Connectors and Adapters are available with 50Ω or 75Ω impedance and operate in a 0GHz to 6GHz frequency range. These lightweight miniature connectors offer reliability, 1500VRMS dielectric withstanding voltage, 1000VRMS voltage rating, and 5000MΩ or 10,000MΩ minimum insulation resistance. Many of the connectors feature bayonet-style coupling for quick connections and disconnections. These connectors are available in 50Ω, 75Ω, and 50Ω reverse polarity. The in-series adapters offer two different interfaces within the same connector series, while between-series adapters include interfaces from different connector series. Applications for Amphenol RF BNC Connectors and Adapters are antennas, telecom, automotive, computers/LANs, medical equipment, Mil-Aero, and much more. A full line of PCB receptacles, bulkhead receptacles, reverse-polarity connectors, resistor terminations, and other accessories complement the product offering.
