The **31-4541-RFX** is a high-quality RF (Radio Frequency) connector manufactured by **Amphenol RF**. It is specifically designed for coaxial cable terminations used in telecommunications, broadcasting, and test equipment. --- ## Technical Specifications | Feature | Specification | | :--- | :--- | | **Connector Type** | BNC Straight Jack (Female) | | **Body Style** | Straight | | **Termination Type** | Crimp | | **Impedance** | 50 Ohm | | **Frequency Range** | 0 - 4 GHz | | **Cable Type Compatibility** | RG-58, RG-141, LMR-195 | | **Mounting Type** | Cable Mount | --- ## Key Material Composition The reliability of the 31-4541-RFX comes from its specific material engineering: * **Body Material:** Brass with **Nickel plating** for durability and corrosion resistance. * **Contact Material:** Phosphor Bronze or Brass with **Gold plating** to ensure low signal loss and prevent oxidation. * **Insulator:** PTFE (Teflon), which provides excellent thermal stability and high dielectric strength. * **Gasket:** Silicone rubber for environmental sealing. --- ## Electronic Performance Characteristics ### 1. Impedance Matching Designed as a **50-ohm** connector, it is optimized for power transfer in RF applications. Using this with 75-ohm systems would cause signal reflections (high VSWR). ### 2. Frequency Handling While BNC connectors are physically robust, this specific part is rated up to **4 GHz**. Performance is most stable within the DC to 3 GHz range, making it ideal for Wi-Fi, GPS, and standard laboratory equipment. ### 3. Voltage Rating It typically supports an operating voltage of approximately **500 Volts RMS** at sea level. --- ## Installation Overview The "RFX" suffix often denotes a commercial-grade series that balances high performance with cost-effectiveness. 1. **Inner Contact:** Usually soldered or crimped to the center conductor of the coax. 2. **Outer Shield:** Secured using a **hex crimp** tool on the outer ferrule. 3. **Bayonet Coupling:** Features the classic "twist and lock" mechanism for quick connect/disconnect without tools.
