The 5222092-3: The right-angle PCB tail and bulkhead mounting feature (front-side nut) let this jack mount flush against a panel while the board runs parallel — a common fit in rack-mount video distribution gear where depth behind the panel is tight.
Impedance and Frequency — the 75 Ohm Difference
A 50 Ohm BNC will physically mate with this jack, but the impedance mismatch at the interface will cause signal reflections and insertion loss above a few MHz. For baseband video (SDI, composite, CCTV) and telecom clock distribution, 75 Ohm is the standard — this jack is built for that path, not for RF test equipment. The 2 GHz bandwidth covers HD-SDI (1.485 Gbps) and 3G-SDI (2.97 Gbps) comfortably, with headroom above. The 500 V rating is higher than most 50 Ohm BNCs (typically 500 V peak, but often derated above 1 GHz). For CCTV systems that run power over coax (Siamese cable) or video distribution amplifiers with DC bias on the line, that voltage margin matters — the dielectric (PMP) holds up without tracking.
Mounting and Termination — Panel Fit and Solder Tail
The shield termination is solder, not a crimp ferrule, so the installer tins the braid and flows solder into the shield cup. The bayonet lock (BNC standard) gives a quarter-turn mate with positive retention; the 500-cycle rating means the gold-on-beryllium-copper centre contact will hold its mating force through years of patch-panel re-patching.
