RF Interconnect for Test and Instrumentation
The 5414460-1: It's a through-hole, solder-terminated PCB-mount connector — the standard footprint for bench test equipment, RF instrumentation, and low-power transmitter stages where a quick-disconnect bayonet is preferred over a threaded SMA. The 500 V rating is higher than a typical 50-ohm BNC, so it handles RF power applications or test fixtures where voltage stress on the dielectric is a concern.
What the 500 Mating Cycles and Gold Plating Mean for Field Service
The gold-plated phosphor bronze centre contact resists corrosion and maintains consistent contact resistance across those cycles — tin plating would wear through and increase VSWR drift long before 500 mates. The nickel-plated zinc body provides adequate RF shielding for indoor environments; if the application sees salt spray or outdoor exposure, the gold-plated stainless steel body of the 1057230-1 peer is a better fit.
