BNC style connectors are miniature, light-weight, weatherproof interconnecting devices characterized by their two-stud, quick disconnect bayonet lock
coupling arrangement. Their design functions satisfactorily from DC to 11 GHz in static applications, or from DC to 4GHz in applications involving
vibration. The connectors typically yield a low VSWR (reflected signal) to 4GHz. Primary applications include radio telecommunications, broadcast
equipment, medical equipment, computer, Precision Video, High definition studio broadcast, video switching and test instrumentation where frequent
coupling and de-coupling are necessary. Bomar’s BNCs are available in an extensive variety of configurations and cable sizes and are impedance
matched to either 50 ohm or 75 ohm.

BNC Twist-On and 2 Piece Crimp
BNC Twist-On connectors are field installable and require no tooling other than a stripping tool for the cable preparation. The center conductor is inserted into Bomar’s
unique Posi-Con ™contact, as the connector is twisted onto the cable’s outer jacket.
BNC 2 Piece crimp connectors make use of a fully captivated pin. Just insert the center conductor into the connector body, slide the ferrule over the braid, and apply a single
hex-crimp to the ferrule. These connectors are easy to install and reliable and are recommended only for the lower data transmission speeds.

BNC PC Board Vertical Jacks
BNC vertical mount jacks are available in straight PC mounts and “through-panel” styles. The “through-panel”, 364 Series, is made in both isolated and
grounded versions and are ideal for applications where multiple insertions will require a connector which can endure the stress of higher torque.

BNC Connectors
BNC PC Board Right Angle JacksX
These BNC jacks are manufactured to the highest standards to assure stability in maintaining impedance matching at 50 ohm and 75 ohm applications.
The 50 ohm versions have been approved by most of the U.S. manufacturers of LAN cards, and the 75 ohm is in wide use in High Definition Video
applications which require the use of a True 75 ohm connector. Contacts are phosphor bronze and will remain resilient even after hundreds of insertions.
