The **W2PE-52A-R** is a specific electronic component, typically categorized as a **D-Subminiature (D-Sub) high-density connector**. These connectors are widely used in computing, telecommunications, and industrial control systems for multi-pin data transmission. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and electrical characteristics. | Feature | Specification | | :--- | :--- | | **Connector Type** | High-Density D-Sub | | **Number of Positions** | 52 Pins | | **Gender** | Plug (Male) | | **Orientation** | Right-Angle (90 degrees) | | **Mounting Type** | Through-hole PCB Mount | | **Termination** | Solder | | **Contact Material** | Copper Alloy (usually Gold plated) | | **RoHS Compliance** | Yes (indicated by the "-R" suffix) | --- ### 2. Physical Design and Construction The "W2PE" series focuses on space-saving on printed circuit boards (PCBs). * **High Density:** Unlike standard D-subs, high-density connectors use three rows of pins instead of two, allowing 52 pins to fit into a shell size similar to a standard 37-pin connector. * **Right-Angle Interface:** The 90-degree bend allows the connector to sit on the edge of a PCB, making the interface accessible from the outside of an enclosure (e.g., a computer backplane). * **Metal Shell:** Usually features a tin-plated or nickel-plated steel shell for EMI/RFI shielding and structural grounding. * **Board Locks:** Typically includes mechanical hardware (like harpoons or screw locks) to ensure the connector stays seated during the soldering process and remains stable under mechanical stress. --- ### 3. Electrical Characteristics | Parameter | Typical Value | | :--- | :--- | | **Current Rating** | 1A to 3A per contact | | **Voltage Rating** | 250V AC/DC | | **Insulation Resistance** | > 1000 MΩ | | **Contact Resistance** | < 15 mΩ | | **Operating Temperature** | -55°C to +105°C | --- ### 4. Common Applications * **Industrial Automation:** Connecting PLCs to sensors and actuators. * **Video Interfaces:** Legacy VGA systems or high-density video routing. * **Telecommunications:** High-speed data links and networking equipment. * **Medical Equipment:** Internal board-to-cable data paths.
