75-ohm HD-BNC plug for broadcast video
The Amphenol 034-1104-12G is an HD-BNC plug — a high-density version of the standard BNC, built for 75 Ohm signal paths. It mates with HD-BNC jacks using a bayonet lock, giving a quick twist-on mate that holds under vibration. The 12 GHz frequency ceiling covers 4K and 12G-SDI broadcast video links without a hitch. This is a three-piece kit: the plug body, a centre contact, and a ferrule. The contact can be crimped or soldered to the centre conductor; the shield is crimped via the ferrule. Rated for 500 mating cycles — good for field-service connectors that get swapped between test gear and production runs.
Cable fit: Belden 4794R
This plug is specced for Belden 4794R cable — a precision 75-ohm coax used in broadcast and pro video. The crimp dimensions and ferrule ID are cut for that cable's jacket and braid diameter. If you're terminating a different 75-ohm coax, check the cable OD and dielectric diameter against the plug's crimp range before ordering.
