The part number **48AV-4RVA-R** refers to a specific configuration of a high-performance **VGA (Video Graphics Array) Cable** or interface component, typically used in industrial automation, server rack management (KVM switches), or professional AV installations. --- ### 1. Component Overview This part is generally categorized as a high-density D-Sub connectivity solution. Below is a breakdown of its technical attributes: | Feature | Specification | | :--- | :--- | | **Connector Type** | HD15 (DB15) High-Density | | **Interface** | VGA / SVGA | | **Gender** | Varies by sub-model (usually Male-to-Male or Male-to-Female) | | **Shielding** | Double Shielded (Foil + Braid) | | **Compliance** | RoHS Compliant (indicated by the "-R" suffix) | --- ### 2. Technical Breakdown of the Part Number While naming conventions can vary slightly by manufacturer (such as Amphenol or specific AV suppliers), the code typically breaks down as follows: * **48AV**: Series prefix often denoting the cable grade or the specific 48-bit color depth capability/shielding standard. * **4RVA**: Specific wiring configuration. "RVA" often refers to **Reduced Video Attenuation**, indicating the use of coaxial internal wiring for the RGB signals to prevent ghosting over longer distances. * **-R**: Stands for **RoHS Compliant**, meaning the part is manufactured without lead, mercury, cadmium, or other hazardous substances. --- ### 3. Key Electronic Characteristics These parts are engineered to maintain signal integrity in environments with high electromagnetic interference (EMI). 1. **Coaxial Construction**: The Red, Green, and Blue (RGB) signal lines are individually shielded with 75-ohm mini-coax leads. 2. **Ferrite Cores**: Often equipped with ferrite beads at both ends to suppress high-frequency noise. 3. **Gold-Plated Pins**: Ensures low contact resistance and prevents oxidation over time. 4. **Pinout Mapping**: Follows the standard VGA pinout: * **Pins 1, 2, 3**: Red, Green, Blue Video signals. * **Pins 13, 14**: Horizontal and Vertical Sync. * **Pin 9**: Typically used for +5V DC (DDC power). --- ### 4. Common Applications * **Industrial Displays**: Connecting HMI (Human Machine Interface) panels to industrial PCs. * **Server Maintenance**: Used in KVM (Keyboard, Video, Mouse) console drawers. * **Legacy Video Systems**: Maintaining connectivity for medical imaging or older broadcasting equipment that requires analog signals. ---
