It is a single-port connector with a solder termination for the shield and center contact. The 75 Ohm impedance makes this the standard choice for video, CCTV, and broadcast signal paths, not the 50 Ohm variant used in telecom or test equipment.
A 50 Ohm BNC plug will physically mate, but the impedance mismatch will cause signal reflections and loss at higher frequencies. The 2 GHz max frequency covers standard-definition and high-definition video well into the multi-GHz range, so it handles 3G-SDI and 12G-SDI signals without issue. The 500 V voltage rating is generous for video and instrumentation circuits, where typical signals are under 10 V. The panel mount uses a front-side nut for bulkhead mounting — the connector body passes through the panel from the front, and a nut tightens from behind. The through-hole solder termination means the center contact and shield legs solder into a PCB, not to a cable. This is a PCB-mount BNC, not a cable-end plug. The nickel-plated zinc body gives good shielding and corrosion resistance for indoor equipment racks. 500 mating cycles is a practical number for a connector that sees regular reconnection. The gold plating on the beryllium copper center contact resists wear and oxidation across those cycles, keeping contact resistance stable. The dielectric is polymethylpentene (PMP), a low-loss plastic that holds the 75 Ohm impedance across the frequency range.
