The 031-70546-12G: It carries a 12 GHz frequency rating, which means it handles the full L-band through X-band spectrum used in video distribution, broadband RF, and test equipment.
This connector is engineered for Belden 4505R — the cable group is specified in the part number, not a generic fit. The nickel body finish and phosphor bronze body material resist corrosion in humid or mildly industrial environments.
The 031-70546-12G is designed for Belden 4505R cable. The cable group is specified in the part — not a generic fit. Using a different cable changes the impedance match and the crimp die requirement.
The gold-plated brass centre contact and nickel body finish support repeated connect-disconnect without signal degradation or corrosion.
Yes, the 031-70546-12G uses a bayonet lock fastening type. The quarter-turn coupling provides a vibration-resistant mate without requiring a torque specification.
