The part number **031-5136-RFX** refers to a high-quality **BNC Straight Plug** (Connector) manufactured by **Amphenol RF**. It is a common component used in telecommunications, radio frequency (RF) applications, and test equipment. --- ### 1. Technical Specifications The "RFX" suffix typically denotes a commercial-grade version of the connector that maintains high performance while being cost-effective for industrial use. | Feature | Specification | | :--- | :--- | | **Connector Type** | BNC Male (Plug) | | **Impedance** | 50 Ohms | | **Body Orientation** | Straight | | **Cable Type** | RG-58, RG-141, RG-142, LMR-195 | | **Termination Type** | Crimp | | **Frequency Range** | 0 - 4 GHz | | **Voltage Rating** | 500 Volts Peak | | **Body Material** | Brass | | **Body Finish** | Nickel | --- ### 2. Physical Construction The connector consists of several key physical parts that ensure a secure electrical connection: * **The Shell (Body):** Made of nickel-plated brass, it features the "bayonet" locking mechanism (twist-and-lock) which allows for quick connect/disconnect. * **The Center Pin:** Usually gold-plated to provide excellent conductivity and prevent oxidation over time. * **The Insulator:** Often made of Delrin or PTFE (Teflon) to keep the center conductor isolated from the outer ground shell. * **The Crimp Ferrule:** A metal sleeve that is compressed over the cable braid to provide a secure mechanical grip and electrical ground. --- ### 3. Assembly and Usage To use this part, specialized tools are required to ensure the signal integrity is maintained: 1. **Stripping:** The coaxial cable (like RG-58) must be stripped to specific dimensions. 2. **Soldering/Crimping:** The center pin is usually soldered or crimped onto the center wire of the cable. 3. **Crimping the Ferrule:** A hex-crimp tool is used to squeeze the ferrule over the cable's outer shielding and the connector tail. ### 4. Common Applications * **Antennas:** Connecting WiFi or Radio antennas to transceivers. * **Laboratory Equipment:** Oscilloscopes and Signal Generators. * **Broadcast:** Video signals (though 75-ohm BNCs are more common for HD video, 50-ohm is used for data). * **Medical Equipment:** Monitoring devices requiring shielded signal paths. ---
