It is a single-port, bulkhead-mount connector with a bayonet lock coupling, rated to 4 GHz with a voltage rating of 500 V. The center contact is gold-plated phosphor bronze, and the body is zinc with nickel finish. This connector is intended for panel-mount installations where a front-side nut secures it to the bulkhead, and the shield is terminated via solder to the body.
The 50 Ohm impedance matches the characteristic impedance of 50 Ohm coaxial cables. The 4 GHz frequency ceiling covers baseband video and RF test signals. The 500 V rating provides headroom for moderate power RF. The 500 mating cycles are typical for a BNC bayonet.
The body is zinc with a nickel finish, providing good RF shielding and corrosion resistance in indoor and sheltered environments. The dielectric is polymethylpentene (PMP), a low-loss plastic that maintains the 50 Ohm impedance across the frequency range. The center contact is phosphor bronze with gold plating — the gold ensures low contact resistance and resists oxidation over the 500-cycle life. The housing color is listed as natural and silver, consistent with the nickel-plated zinc body. The package is Tube, meaning it ships in a rigid tube for protection during handling.
Mating and installation
The mounting feature is bulkhead front-side nut: the connector body passes through a panel hole, and a nut tightens from the front side, securing it flush to the panel. The shield termination is solder: the braid or foil of the coaxial cable is soldered to the body or a solder cup. The center contact termination is also solder, so the cable center conductor is soldered to the pin. The board guide and isolated features (per the spec listing) aid alignment and prevent ground loops in PCB-mount variants, though this is a panel-mount part.
