Product details

BNC Jack-to-Jack Adapter, 50 Ohm, 4 GHz — Last Buy

The UG-414/U(40) is a BNC-series, straight, jack-to-jack adapter with female center contacts on both ends, designed for same-series BNC-to-BNC coupling. It mates two BNC male connectors — typically extending a cable run or linking two cables through a bulkhead. The 50-Ohm impedance and 4 GHz maximum frequency suit it for RF test setups, telecommunications infrastructure, and instrumentation where signal integrity through the adapter must not introduce a mismatch. The panel-mount flange lets it bolt into a standard BNC panel cutout, acting as a fixed bulkhead feedthrough.

Materials and Build for RF Duty

Silver plating on both body and contacts gives low contact resistance and good corrosion resistance for indoor RF environments. The beryllium copper center contacts maintain spring force over 10000 mating cycles — well above the typical BNC adapter rating, which means this adapter can handle frequent reconnections in test or patch-panel use without the center contact losing grip.

As a BNC-to-BNC adapter with female N-feedthrough contacts on both ends, it accepts any standard BNC male plug. The panel-mount flange uses the standard BNC bulkhead hole pattern — no special cutout needed. The straight body orientation keeps the cable axis aligned with the panel plane.

Frequently asked questions

What is the impedance of UG-414/U(40)?

The UG-414/U(40) is a 50-Ohm impedance adapter, matching the standard for BNC RF systems.

Does UG-414/U(40) fit a standard BNC panel cutout?

Yes, the panel-mount flange is designed for the standard BNC bulkhead hole pattern. No special cutout is required.

How many mating cycles does UG-414/U(40) support?

The UG-414/U(40) is rated for 10000 mating cycles, enabled by the beryllium copper center contacts and silver plating.
