The **W2TG0-321-R** is a specific part number belonging to the **W2 Series** of high-performance connectors, typically manufactured by **Winchester Interconnect (formerly Winchester Electronics)**. These components are designed for high-density, high-speed backplane applications. --- ### 1. Component Overview The W2 series is characterized by its high-density signal integrity and modular design. The "321" designation typically refers to the specific configuration of rows, columns, or pin density. | Feature | Specification | | :--- | :--- | | **Product Category** | High-Density Backplane Connector | | **Series** | W2 (High-Speed) | | **Mounting Type** | Press-fit (Solderless) | | **Contact Plating** | Gold over Nickel (R-Suffix usually denotes RoHS compliance) | | **Application** | Data centers, Telecommunications, Industrial Computing | --- ### 2. Key Technical Characteristics #### A. High-Speed Performance These connectors are engineered to handle high data rates (often 10 Gbps and above) while minimizing: * **Crosstalk:** Reducing interference between adjacent signal pins. * **Insertion Loss:** Ensuring signal strength is maintained over the connection. #### B. Press-Fit Technology The "W2" series often utilizes eye-of-the-needle press-fit pins. * **Benefit:** Allows for easy installation onto Printed Circuit Boards (PCBs) without the thermal stress of soldering. * **Reliability:** Provides a gas-tight connection that is highly resistant to vibration. #### C. Modular Design The part is part of a modular system where headers (male) and receptacles (female) can be arranged in various grid patterns to suit custom backplane architectures. --- ### 3. Typical Pin Configuration Structure While exact specifications depend on the manufacturer's specific datasheet for the "321" variant, the numbering usually follows this logic: | Digit Position | Meaning | | :--- | :--- | | **W2** | Series Identifier (Backplane family) | | **TG** | Connector Type (e.g., Right Angle, Vertical, or Header) | | **321** | Specific configuration (No. of pins, rows, or specific mechanical keying) | | **R** | RoHS Compliant / Lead-free status | --- ### 4. Application Areas * **Blade Servers:** Connecting vertical processing blades to a horizontal backplane. * **Network Switches:** High-throughput data routing hardware. * **Medical Imaging:** Transferring large volumes of raw data between sensor arrays and processors.
