Amphenol Rf 031-219 Bnc Jack to Bnc Jack Adapter 50 Ohm

Product Description

The AMPHENOL RF 031-219 is a UG-914/U BNC jack to BNC jack adapter rated at 50 ohms impedance. This inline barrel adapter connects two BNC male plugs end-to-end, extending or joining coaxial cable runs without signal degradation across the interface. It is a passive RF connector accessory used in coaxial signal distribution, test bench setups, and field wiring applications. Installation is straightforward and does not require tools beyond hand-tightening the mating connectors. Technicians working in RF signal routing, communications wiring, or instrumentation installations use this type of adapter to bridge two cable segments or connect equipment with BNC male outputs.

This adapter is suited for coaxial cable systems operating at 50 ohms characteristic impedance. Typical applications include RF test equipment connections, antenna feed lines, signal distribution panels, and low-voltage communications infrastructure in both residential and commercial environments. It is sold as an individual unit and is compatible with standard BNC male plug connectors on both mating ends.

Key Features

• UG-914/U military-designation BNC jack to BNC jack inline barrel configuration
• 50 ohm impedance matches standard coaxial system requirements
• Accepts BNC male plugs on both ends for direct cable-to-cable or equipment-to-cable connection
• Passive adapter with no active components — no power required
• Compact form factor for use in tight wiring spaces or on patch panels

Compatibility

Designed as an OEM-style inline adapter for use with standard 50 ohm BNC male plug connectors in coaxial RF and signal distribution systems.

Installation Notes

This adapter is installed by hand-threading standard BNC male plugs into each port until the bayonet lock engages. No special tools are required. Ensure coaxial cable assemblies are de-energized or disconnected from active signal sources before making or breaking connections on live RF systems. Follow applicable low-voltage wiring codes and facility standards when integrating into permanent signal distribution infrastructure.
