What is the 5227755-1 connector?
It ships as a three-piece kit: the connector body, a mounting nut, and a separate solder tag for shield termination. The 4 GHz bandwidth and 500 mating cycles put it in the standard-duty class for test equipment, telecom infrastructure, and instrumentation racks where the connector stays mated most of its life but sees occasional field swaps.
50 Ohm impedance, 4 GHz max frequency, 500 mating cycles. The panel mount uses a rear-side nut (bulkhead style) with a solder tag for the shield braid — the installer tins the braid and solders it to the tag rather than relying on a crimp ferrule. The centre contact terminates via solder cup, so the cable prep needs to be clean and the centre conductor tinned before insertion. Body is zinc with nickel finish, the centre contact is phosphor bronze with tin plating — adequate for the 500-cycle life but not a high-cycle gold-plated contact. The PBT dielectric holds the centre pin concentric for consistent 50 Ohm through the interface. The extended insulation feature (noted on the listing) means the dielectric protrudes slightly past the mating face, which reduces the risk of voltage flashover in high-humidity environments at the 500 V rating.
Is 5227755-1 still in active production?
No official replacement or cross-reference has been issued, so this remains the direct BOM line part.
