The 031-70572-12G: Rated to 12 GHz, it handles high-frequency signals well beyond baseband video, making it suitable for HD-SDI and other serial digital interfaces. The bayonet lock provides quick, secure mating, and the gold-plated center contact ensures low and stable contact resistance over 500 mating cycles.
Crimp Termination and Cable Compatibility
The cable group is specified for Belden 4505P — a 75 Ohm precision video coax. Using a different cable changes the crimp die size and the impedance match, so stick with the listed cable or verify the crimp dimensions against the manufacturer's drawing.
Mating and Mechanical Fit
Mating a 75 Ohm plug to a 50 Ohm jack creates a reflection at the interface that degrades return loss. The bayonet lock engages with a quarter-turn, and the nickel-plated phosphor bronze body resists corrosion. The free-hanging (in-line) mounting is typical for cable assemblies; no panel cutout or bulkhead hardware is needed.
