The part number **31-335-RFX** refers to a specific type of **BNC (Bayonet Neill–Concelman) RF Connector** manufactured by **Amphenol RF**. It is a commercial-grade connector designed for coaxial cables, commonly used in radio frequency applications. --- ### 1. Technical Specifications The following table summarizes the key electrical and physical characteristics of the 31-335-RFX: | Property | Specification | | :--- | :--- | | **Connector Type** | BNC Straight Plug (Male) | | **Impedance** | 50 Ohms | | **Cable Type** | RG-58, RG-141, RG-142, LMR-195 | | **Frequency Range** | 0 - 4 GHz | | **Termination Style** | Crimp / Solder | | **Body Material** | Brass | | **Body Plating** | Nickel | | **Contact Plating** | Gold | | **Insulator Material** | Delrin | --- ### 2. Key Components and Design The "RFX" suffix in Amphenol part numbers typically denotes a **commercial-grade** version of the connector. While it maintains high performance, it is optimized for cost-effective industrial and consumer applications rather than military-spec (MIL-SPEC) requirements. * **Bayonet Locking Mechanism:** Features the classic "twist and lock" system, allowing for quick connect/disconnect without tools. * **Interface:** Standard BNC interface, ensuring compatibility with most oscilloscopes, signal generators, and antennas. * **Crimp Termination:** The outer braid is secured using a hex crimp tool, while the center conductor is usually soldered or crimped to the center pin. --- ### 3. Common Applications This connector is widely used in sectors requiring reliable RF signal transmission: 1. **Test and Measurement:** Connection for oscilloscopes and function generators. 2. **Telecommunications:** Used in base stations and radio transmission equipment. 3. **Security Systems:** Connecting CCTV cameras using RG-58 coaxial cabling. 4. **Wireless Infrastructure:** Standard for Wi-Fi antennas and GPS systems. --- ### 4. Assembly Overview To properly install the 31-335-RFX, the following steps are generally required: 1. **Strip the Cable:** Remove the outer jacket, braid, and dielectric to the dimensions specified in the Amphenol datasheet. 2. **Solder/Crimp Pin:** Attach the center contact pin to the cable's center conductor. 3. **Insert Body:** Push the connector body over the pin until it snaps into place. 4. **Crimp Ferrule:** Slide the metal ferrule over the braid and the connector tail, then compress it using a **0.213" hex crimp tool**.
