BNC MALE Connector

BNC Family

BNC (Bayonet Neill–Concelman) is a quick-connect RF connector featuring a bayonet locking mechanism for fast mating and unmating, rated from DC to 4 GHz. Its ease of use makes it standard in test and measurement equipment, video distribution, two-way radio accessories, and laboratory bench setups where cables are frequently connected and disconnected.

Typical Applications

Test and measurement equipment, oscilloscope probes, video distribution, two-way radio accessories, surveillance camera coax, baseband signal patching.

Gender & Polarity Note

Check the product datasheet for gender and polarity details. RF connectors are available in male (pin), female (socket), and reverse-polarity (RP) variants.

Frequently Asked Questions

What frequency range does the BNC MALE connector support?

BNC connectors are rated DC – 4 GHz. The effective upper frequency of a cable assembly is limited by the lowest-rated component — either the cable or the connector. Always verify both are within spec for your target frequency.

How many times can a BNC connector be mated and unmated?

BNC MALE connectors are rated for approximately 500 mating cycles. Exceeding this can cause wear on the contact surfaces, increasing insertion loss and VSWR. For applications with very frequent connects and disconnects, consider a connector rated for higher cycle counts.

What torque should I use to tighten a BNC connector?

BNC connectors use a quarter-turn bayonet lock — no torque wrench is needed. Ensure the coupling nut is fully seated and locked to avoid intermittent connections.

Are the BNC connectors on CoaxRF assemblies weatherproof?

Our standard cable assemblies use high-quality connectors suitable for most indoor and sheltered outdoor applications. For fully weatherproof outdoor installations, we recommend applying self-amalgamating tape over the connector junction to prevent moisture ingress.

Do CoaxRF cables with BNC MALE connectors ship assembled and tested?

Yes. Every cable assembly — including those terminated with BNC MALE connectors — is hand-assembled and continuity tested before shipping. Cables ship free within the US from our US facility.
