That 12 GHz ceiling means the center contact and dielectric geometry are held to tighter tolerances, so the connector maintains a clean 75 Ohm transmission line all the way up. In a broadcast truck or test rack where a camera feed gets re-patched daily, 500 cycles translates to years of service before the contact resistance drifts. ## Mounting Options: Board Edge or Panel The 031-70526-12 gives two mounting paths in one part. As a board edge end-launch, the solder legs land directly on PCB traces at the board edge — useful when the BNC needs to sit flush with the enclosure wall and the PCB routes right up to the edge. As a panel-mount bulkhead, the front-side nut clamps the jack to a chassis cutout, and the lockwasher prevents the nut from backing off under vibration.","metaTitle":"Amphenol RF 031-70526-12 BNC Jack, 75 Ohm, 12 GHz","metaDescription":"Amphenol RF 031-70526-12 BNC jack, female socket, 75 Ohm impedance, 12 GHz max frequency, 500 mating cycles.
