BNC RF connectors are the most popular coaxial connector. The special bayonet design allows easy mating and unmating. BNC 50 ohm connectors provide repeatable electronic performance from DC to 4 GHz. BNC 75 ohm connectors are suitable for applications up to 1 GHz. All 50 and 75 ohm connectors are intermatable. BNC type connectors are designed to accomodate a large variety of RG and industry standard cables. They are available in crimp, clamp, and twist on cable styles. A full line of printed circuit board receptacles, bulkhead receptacles, and other accessories complement the product offering. LTI BNC connectors are designed to conform to MIL-C-39012 specifications.

The BNC series coaxial connector works well in lower microwave frequency applications including monitors, LAN, telecommunication devices and test equipment.
