UHF Bulkhead Receptacle — What You're Getting
The Amphenol 83-878-RFX is a UHF-series receptacle, female socket, built for panel-mount bulkhead installations where a threaded, front-side-nut retention is needed. Rated for 500 V and a maximum frequency of 300 MHz, this connector is for HF through low UHF bands. The centre contact is silver-plated brass, terminated via a solder cup — a classic field-repairable termination that any tech with a soldering iron and a heat source can handle on site. Body is zinc die cast with a nickel finish, silver in colour. Rated for 500 mating cycles — enough for occasional disconnect in test or maintenance scenarios, but not a daily-mate production connector.
Mating and Field Fit
The solder cup termination accepts a range of wire gauges typical for RF cable assemblies — centre conductor sizes that fit the cup. No special crimp tool needed; just tin the wire, fill the cup, and let it cool. The bulkhead mounting feature (front side nut) means the receptacle installs from the outside of the panel, with the nut and lockwasher securing it from the inside.
Cross-Shop: UHF Plug vs This Receptacle
If you're sourcing both halves of a UHF interconnect, the 083-8SP-1006 is the plug (male pin) counterpart to this 83-878-RFX receptacle. Both are Amphenol UHF-series, both rated for 500 V and 300 MHz, both use the threaded coupling interface. The plug terminates via crimp for shield and crimp for centre conductor — a different termination style than the solder cup on this receptacle. The plug is also a single-piece unit (no included hardware), while this receptacle ships with the lockwasher and nut for panel mounting.
