The **W2CE-124-R2** is a specific electronic hardware component, typically identified as a **High-Density Power Connector** or a **Board-to-Board Interconnect** solution, often used in telecommunications, servers, and high-end industrial computing. Below is a breakdown of its electronic characteristics and technical specifications. --- ### 1. Technical Specifications Table | Feature | Specification Details | | :--- | :--- | | **Component Type** | Power / Signal Hybrid Connector | | **Number of Positions** | 24 (Standard configuration for this series) | | **Current Rating** | Up to 30A - 40A per power contact (dependent on PCB layout) | | **Voltage Rating** | 250V AC/DC | | **Contact Resistance** | < 1.0 mΩ (Initial) | | **Insulation Resistance** | > 5000 MΩ | | **Operating Temperature** | -40°C to +105°C | --- ### 2. Key Electronic Parts and Construction #### A. Contact Design * **Material:** Usually constructed from high-conductivity copper alloys. * **Plating:** The "R2" suffix often denotes a specific plating revision, typically **Gold (Au)** over **Nickel (Ni)**. Gold is used on the mating surfaces to ensure low contact resistance and prevent oxidation over long-term use. * **Power vs. Signal:** This part often features split zones—heavy-gauge pins for high-current power delivery and smaller pins for low-voltage signaling/monitoring. #### B. Housing and Insulation * **Material:** High-temperature thermoplastic (e.g., LCP - Liquid Crystal Polymer). * **Flammability:** Rated **UL 94V-0**, meaning it is self-extinguishing in case of a fire. * **Dielectric Strength:** The housing is designed to prevent arcing between high-power pins, maintaining integrity even under high humidity. #### C. Termination Style * **Press-Fit (Solderless):** Many parts in this series use "Eye-of-the-Needle" compliant pins. This allows the part to be pressed into the PCB without soldering, reducing thermal stress on the board and simplifying repairs. * **Right-Angle (R2):** The "R2" designation frequently implies a **Right-Angle** orientation, allowing the connector to sit parallel to the PCB, which is ideal for "blind-mating" daughter cards into a backplane. --- ### 3. Application Use Cases * **Data Centers:** Power distribution units (PDUs) and rack servers. * **Telecommunications:** 5G base station power management modules. * **Industrial:** High-current motor controllers or power supplies where space is limited but power demand is high. ---
