The part number **31-71014-RFX** refers to a high-quality **BNC Straight Crimp Plug** manufactured by **Amphenol RF**. This specific connector is part of their "RFX" line, which is designed to provide consistent performance in commercial applications while remaining cost-effective. --- ### 1. Key Technical Specifications Below are the primary physical and electrical characteristics of the 31-71014-RFX: | Property | Specification | | :--- | :--- | | **Connector Type** | BNC Male (Plug) | | **Body Style** | Straight | | **Impedance** | 50 Ohm | | **Cable Type** | RG-58, RG-141, RG-142, LMR-195 | | **Termination Type** | Crimp / Solder | | **Frequency Range** | 0 - 4 GHz | | **Coupling Mechanism** | Bayonet (Twist-on) | | **Plating** | Nickel (Body), Gold (Contact) | --- ### 2. Component Breakdown The 31-71014-RFX typically consists of four main physical pieces included in the kit: 1. **Main Body:** The nickel-plated housing featuring the bayonet locking mechanism and the internal dielectric (insulation). 2. **Male Pin (Center Contact):** Usually gold-plated to ensure low contact resistance and prevent oxidation. This is soldered or crimped onto the center conductor of the coaxial cable. 3. **Crimp Ferrule:** A metal sleeve that is slid over the cable jacket and crimped down to secure the cable's outer braid to the connector body. 4. **Insulator:** Internal PTFE or similar material that maintains the 50 Ohm impedance spacing. --- ### 3. Common Applications This connector is widely used in industries requiring secure, quick-disconnect radio frequency (RF) connections: * **Test and Measurement:** Oscilloscope leads and signal generators. * **Telecommunications:** Base stations and wireless communication hardware. * **Video Systems:** Professional broadcast video and CCTV (though 75 Ohm is more common for HD-video, 50 Ohm is used for specific data signals). * **Antennas:** Connecting low-power RF antennas to transmitters or receivers. --- ### 4. Installation Requirements To install this part correctly, specific tools are required: * **Coaxial Cable Stripper:** To prepare the RG-58 or equivalent cable to the correct dimensions. * **Crimp Tool:** A hex-crimp tool (usually with a .213" hex cavity) to secure the ferrule. * **Soldering Iron:** (Optional) If the center pin is being soldered rather than crimped.
