The nickel-plated brass body gives the shell a consistent ground reference and resists corrosion in indoor or sheltered outdoor enclosures. ## Mounting Options — Board-Edge End Launch or Panel Feedthrough The 031-70526-11 supports two mounting modes. For a PCB-edge RF launch, the end-launch solder terminals let the centre contact and shield solder directly to the board — the signal path stays short and the impedance transition is controlled. For a panel feedthrough, the bulkhead flange with front-side nut clamps the connector to a chassis or enclosure wall; the lockwasher prevents the nut from backing off under vibration. The bayonet lock (BNC standard) gives a quarter-turn mate that locks positively without threads — fast to connect and disconnect in the field, and the 500-cycle mating life means it holds up to regular service access. ## What the 12 GHz Ceiling and 75 Ohm Mean for Your Signal Path The 12 GHz frequency maximum is high for a 75 Ohm BNC — most 75 Ohm BNCs are specified to 1-4 GHz for video baseband. The 12 GHz rating means this jack supports higher-frequency modulated signals or digital data streams well beyond standard-definition video, though the usable bandwidth in a real system also depends on the cable and the mating plug's performance. The 75 Ohm impedance is non-negotiable for the system: a 75 Ohm jack on a 50 Ohm line creates a reflection at the junction. Match it with 75 Ohm cable and a 75 Ohm BNC plug.","metaTitle":"Amphenol RF 031-70526-11 BNC Jack, 75 Ohm, 12 GHz","metaDescription":"Amphenol RF 031-70526-11 BNC jack, 75 Ohm impedance, rated to 12 GHz.
