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, 1500V_RMS dielectric withstanding voltage, 1000V_RMS 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.
