The **A-MCSSP60030-B-R** is a specific technical component, typically identified as a **shielded modular plug (RJ45)** used in high-performance networking applications. It is designed for field termination or assembly onto Ethernet cables (Cat6/Cat6a). Below is a detailed breakdown of its electronic and mechanical specifications. ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Connector Type** | RJ45 (8P8C) Modular Plug | | **Shielding** | Shielded (STP/FTP) with Metal Shell | | **Performance Category** | Cat6 / Cat6a (up to 10Gbps) | | **Contact Plating** | 50 micro-inches Gold Plating | | **Cable Type** | Round Cable, Solid or Stranded wire | | **Wire Gauge Compatibility** | Typically 23 AWG to 26 AWG | | **Housing Material** | Polycarbonate (UL 94V-0 or 94V-2) | --- ### 2. Key Electronic Components The "parts" of this modular plug function together to ensure signal integrity and grounding: * **Gold-Plated Contacts:** The 50μ" gold plating is critical for preventing oxidation and ensuring a low-resistance electrical connection between the cable and the jack. * **Shielding Shell:** The outer metal casing (usually nickel-plated brass) acts as a Faradic cage. It connects to the cable's drain wire to provide EMI/RFI protection, which is essential for maintaining speeds in high-interference environments. * **Load Bar (Internal):** Many versions of this series include a load bar (a small plastic guide). This aligns the twisted pairs precisely before they are crimped, minimizing **NEXT** (Near-End Crosstalk). * **Insulation Displacement Contacts (IDC):** The internal metal teeth pierce the wire insulation to create a gas-tight electrical bond with the copper conductors. --- ### 3. Part Number Breakdown (Typical) While part numbering schemes vary by manufacturer (often ASSMANN WSW components), the code generally breaks down as follows: * **A-MCSS:** High-speed Shielded Modular Plug series. * **P60030:** Specific dimensional configuration (often referring to the max wire OD or the specific Cat6/6a internal geometry). * **B:** Often denotes bulk packaging or a specific color/material variant. * **R:** Generally indicates **RoHS Compliance** (Restriction of Hazardous Substances). --- ### 4.
