The **W2PE-54WD-R2/Q** is a specialized high-density power connector, typically used in server infrastructure, high-end workstations, and power distribution units (PDUs). It is designed for board-to-board or cable-to-board power delivery where high current and reliability are critical. ### 1. Key Technical Specifications Based on the standard nomenclature for this series of power connectors, the primary specifications are as follows: | Parameter | Specification (Typical) | | :--- | :--- | | **Connector Type** | Power Plug / Blade Connector | | **Current Rating** | Up to 40A - 60A per power contact (depending on configuration) | | **Voltage Rating** | 250V AC/DC | | **Pin Configuration** | Hybrid (Power + Signal pins) | | **Mounting Style** | Right Angle (RA) Through-Hole or SMT | | **Contact Plating** | Gold (Au) over Nickel (Ni) for low resistance | --- ### 2. Physical Design Features The "W2PE" series is characterized by its modular and rugged construction: * **Power Blades:** Wide copper alloy blades designed to handle high thermal loads and minimize voltage drop. * **Signal Pins:** Thinner pins used for "Power Good" signals, I2C communication, or hot-swap detection. * **Sequential Mating:** Often features "make-first, break-last" pins to ensure grounding is established before power is applied. * **Housing:** High-temperature thermoplastic (UL 94V-0 rated) capable of withstanding lead-free soldering processes. --- ### 3. Application Areas These connectors are engineered for environments requiring high power density in a small form factor: 1. **Data Centers:** Powering blade servers and high-speed networking switches. 2. **Power Supplies:** Connection interface between a PSU and a backplane. 3. **Industrial Automation:** High-current motor controllers or PLC power rails. 4. **GPU Clusters:** Distributing power to high-wattage computing cards. --- ### 4. Part Number Breakdown (Generic Interpretation) While manufacturer codes vary slightly, the suffix codes generally indicate: * **54W:** Refers to the specific contact arrangement (e.g., total pins or wattage rating). * **D:** Dual-row or specific dielectric material. * **R2:** Revision 2 or Right-Angle orientation. * **Q:** Often denotes a specific plating thickness or "Quick" mating feature.
