The **M2PHSL-BB-R/CE** is a specialized high-speed connector, typically part of a modular backplane system used in telecommunications and data networking equipment. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. General Overview This part belongs to the **High-Speed Mezzanine** or **Backplane** connector family. It is designed to facilitate the connection between a daughtercard and a motherboard (backplane) while maintaining high signal integrity. | Attribute | Specification | | :--- | :--- | | **Product Category** | High-Speed Backplane Connector | | **Series** | M2PH Series (Modular High Speed) | | **Gender** | Header / Plug (Male) | | **Orientation** | Vertical / Straight | | **RoHS Status** | Compliant (CE Marked) | --- ### 2. Key Technical Specifications #### Signal Integrity & Performance * **Data Rate:** Designed to handle differential signals at high speeds (often 10 Gbps to 25 Gbps depending on the specific revision). * **Impedance Control:** Tight tolerance (usually $100 \Omega$ or $85 \Omega$) to prevent signal reflections. * **Contact Plating:** Gold over Nickel (Gold-plating is essential for high-frequency low-loss transmission). #### Electrical Characteristics * **Current Rating:** Typically 0.5A to 1.0A per pin (Signal pins). * **Voltage Rating:** ~125V AC/DC. * **Insulation Resistance:** $>500 M\Omega$ minimum. --- ### 3. Physical & Mechanical Construction | Component | Material / Feature | | :--- | :--- | | **Housing** | High-temperature Liquid Crystal Polymer (LCP) - UL94V-0 rated. | | **Mounting Style** | Press-fit (Compliant Pin) or Surface Mount (SMT) - typically Press-fit for backplanes. | | **Termination** | Eye-of-the-needle (EON) compliant pins to minimize PCB hole damage. | | **Shielding** | Integrated ground planes to minimize crosstalk between differential pairs. | --- ### 4. Part Number Breakdown (Typical) While internal manufacturer codes vary, the suffixing usually indicates: * **BB:** Often refers to the Body Height or Stack Height (e.g., "Board-to-Board"). * **R:** Tape and Reel packaging or Right-angle/Revised orientation. * **CE:** Compliance mark (European Conformity). --- ### 5. Application Areas * **Networking:** Switches, Routers, and Hubs. * **Computing:** Server blades and High-Performance Computing (HPC) clusters. * **Industrial:** Modular control systems requiring high data throughput. ---
