The **PDI-CAA-RVGXX** series refers to a specific line of **Ruggedized High-Definition (HD) Video Cables** manufactured by **PDI Communication Systems**. These cables are primarily designed for healthcare, commercial, and industrial environments where durability and signal integrity are critical. Below is a detailed breakdown of the electronic components and technical specifications. --- ### 1. Technical Specifications The "RVG" in the part number typically signifies the "Rugged Video Grade" construction. | Feature | Specification Details | | :--- | :--- | | **Connector Type** | Dual HDMI (Standard Type A) | | **Signal Support** | 1080p HD, 4K (Model dependent), and 3D Video | | **Shielding** | Triple-layer foil and braid shielding for EMI/RFI protection | | **Conductor Material** | High-purity Oxygen-Free Copper (OFC) | | **Jacket Material** | Heavy-duty, high-flex PVC or Plenum-rated material | | **Impedance** | 100 Ohms (Standard for HDMI Differential Pairs) | --- ### 2. Key Electronic Components #### A. Internal Conductors The cable utilizes **28 AWG or 30 AWG stranded copper wires**. Because these cables are often used on articulating arms (like those holding TVs in hospital patient rooms), the copper is finely stranded to prevent "metal fatigue" or internal snapping after thousands of bends. #### B. Active vs. Passive Circuitry * **Passive Versions:** Shorter lengths (under 15ft) rely on high-quality copper to maintain signal timing. * **Active Versions (XX > 20ft):** For longer runs, these parts may include a small **Equalizer Chipset** embedded in the "Sink" (Display) end of the connector to boost the digital signal and compensate for attenuation. #### C. Shielding Layers To prevent interference from medical equipment (like X-ray or MRI machines nearby), these cables use: 1. **Individual Pair Shielding:** Al-Mylar foil around data pairs. 2. **Overall Foil Shielding:** 100% coverage. 3. **Tinned Copper Braid:** Provides structural strength and low-frequency interference protection. --- ### 3. Structural Design Features The "Rugged" aspect of the PDI-CAA-RVGXX series includes specific mechanical-electronic reinforcements: * **Strain Relief:** Over-molded heavy-duty boots prevent the internal solder joints from pulling away from the connector pins. * **Gold-Plated Contacts:** 24K Gold plating is used on the pins to prevent oxidation in humid environments, ensuring a low-resistance electronic connection over time. * **Friction Fit:** The metal housings are often designed with high-retention force to prevent the cable from vibrating loose. --- ### 4.
