The part number **31-336-RFX** refers to a high-quality **BNC Straight Plug (Connector)** manufactured by **Amphenol RF**. This specific part is designed for coaxial cable termination and is widely used in radio frequency (RF) applications. --- ### 1. Technical Specifications The following table outlines the primary electrical and mechanical characteristics of the 31-336-RFX: | Feature | Specification | | :--- | :--- | | **Connector Type** | BNC (Bayonet Neill–Concelman) | | **Gender** | Male (Plug) | | **Impedance** | 50 Ohms | | **Body Material** | Brass | | **Body Finish** | Nickel | | **Contact Material** | Brass (Male Pin) | | **Contact Plating** | Gold | | **Mounting Type** | Cable Mount (Crimp/Solder) | | **Cable Group** | RG-58, RG-141, RG-142, LMR-195 | | **Frequency (Max)** | 4 GHz | --- ### 2. Key Component Materials The "RFX" designation often indicates a commercial-grade series from Amphenol that balances high performance with cost-effectiveness. * **Shell/Body:** Made of Nickel-plated brass for durability and corrosion resistance. * **Center Contact:** Gold-plated to ensure low signal loss and prevent oxidation over long periods. * **Insulator:** Typically made of **Delrin** or **PTFE (Teflon)** to maintain constant impedance and provide high dielectric strength. * **Coupling Mechanism:** Uses a bayonet-style "twist and lock" mechanism for quick connect/disconnect and secure vibration resistance. --- ### 3. Application and Usage This connector is typically paired with **RG-58** or similar 50-ohm coaxial cables. It is commonly found in: 1. **Test Equipment:** Oscilloscopes, signal generators, and spectrum analyzers. 2. **Antenna Systems:** Low-power RF transmissions and WLAN setups. 3. **Broadcast Video:** Standard definition video signals (though 75-ohm BNCs are more common for professional HD video). 4. **Medical Equipment:** Monitoring devices requiring secure signal paths. ### 4. Installation Method The 31-336-RFX is a **Crimp-on** connector. The assembly process usually follows these steps: 1. Strip the outer jacket, braid, and dielectric of the coax cable. 2. Slide the crimp ferrule onto the cable. 3. Solder or crimp the center pin onto the center conductor. 4. Push the connector body over the pin until it clicks. 5. Slide the ferrule over the braid and use a hex-crimp tool to secure it. ---
