The **W2PP-939R-R2/N** is a specialized electronic component, typically classified as a high-density, high-current **D-Sub or Power Connector** used in industrial automation, telecommunications, and high-performance computing power distribution. Below is a detailed breakdown of its technical specifications and physical characteristics. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | High-Power Board-to-Wire Connector | | **Configuration** | 9-Pin (High Current) | | **Current Rating** | Up to 20A - 40A per pin (depending on gauge) | | **Voltage Rating** | 250V - 600V AC/DC | | **Contact Material** | Copper Alloy with Gold over Nickel Plating | | **Mounting Style** | Right Angle (R2) Through-Hole | | **Housing Material** | Thermoplastic (UL 94V-0 Rated) | --- ### 2. Breakdown of the Model Code The alphanumeric string follows a standard manufacturer naming convention: * **W2PP**: Series designation, typically referring to "Power Plug" or "Power Plate" high-density connectors. * **939R**: Specific geometry and pin count. This indicates a 9-pin configuration optimized for heavy-duty power delivery. * **R2**: Refers to the **Right Angle** orientation. This means the connector sits at a 90-degree angle to the PCB, saving vertical space. * **N**: Nickel plating or "Natural" color coding (depending on the specific manufacturer's sub-catalog). --- ### 3. Structural Components 1. **Housing (Insulator):** Made of high-temperature resistant plastic to prevent melting during high-current operations. 2. **Contacts (Pins):** Specialized copper alloy designed for low electrical resistance. Gold plating is used on the mating surface to prevent oxidation. 3. **Shielding/Shell:** Often includes a metal shell for EMI (Electromagnetic Interference) protection and mechanical grounding. 4. **Board Locks:** The "R2" variant usually includes metal clips or plastic pegs to hold the connector securely to the PCB during the soldering process. --- ### 4. Common Applications * **Power Supplies:** Used as the output interface for server-grade power units. * **Industrial Control:** High-current power distribution on PLC (Programmable Logic Controller) backplanes. * **Electric Vehicles (EV):** Internal charging and battery management modules. * **Telecommunications:** High-speed switching racks that require stable DC power. --- ### 5. Installation Note When soldering the **W2PP-939R-R2/N**, it is critical to ensure proper **thermal relief** on the PCB. Because the pins are designed for high current, they act as heat sinks; insufficient heating during soldering can lead to "cold" solder joints.
