It carries a 2 GHz frequency maximum and 500 mating cycles, with a gold-plated brass center contact and nickel-plated zinc die-cast body. The bayonet lock gives quarter-turn coupling — no tool needed for field mate/demate. This is a single-port connector from the Greenpar series, built for video distribution, baseband digital, and telecom equipment where 75 Ohm characteristic impedance is standard.
The 75 Ohm impedance defines the signal path — this is not a 50 Ohm BNC. Swapping them on a 75 Ohm line (CCTV, broadcast video, telecom T1/) causes a mismatch that reflects signal energy. The 2 GHz ceiling covers composite video (baseband to ~6 MHz) and digital video (SDI up to 1.485 Gbps) with margin; above 2 GHz the return loss degrades. 500 mating cycles is a solid field-service figure — the gold-plated center contact handles repeated reconnection without fretting corrosion, but the bayonet lock's detent spring will wear before the contact does.
Panel mount with a front-side bulkhead nut secures the connector to the chassis; the right-angle through-hole pins solder into the PCB. The dielectric is polyethylene (PE), which sets the 75 Ohm impedance for the given center conductor and outer body dimensions. The body finish is nickel over zinc die cast; the housing color is listed as black and silver.
