The **M2PHS2H-C4-R2/CE** is a specialized electronic component, typically classified as a high-density, high-speed connector or module often used in industrial automation, telecommunications, or server backplane environments. Below is a breakdown of its technical characteristics and electronic composition. --- ### 1. Technical Specifications Overview This part is designed for precision signal integrity and durable electrical contact. | Feature | Specification | | :--- | :--- | | **Component Type** | High-density Header / Power-Signal Hybrid | | **Configuration** | 2-Row (typical for PHS series) | | **Contact Material** | Copper Alloy with Gold (Au) plating | | **Housing Material** | High-temperature Thermoplastic (UL94V-0) | | **Mounting Type** | Through-hole or SMT (depending on R2 suffix) | | **Current Rating** | High Current capacity for Power pins (up to 30A+) | --- ### 2. Electronic Component Breakdown #### A. Signal Integrity (SI) Design The "PHS" designation often refers to **Power and High-Speed** integration. * **Impedance Control:** The internal geometry is designed to maintain 85Ω or 100Ω differential impedance to prevent signal reflections. * **Crosstalk Reduction:** The shielding pins and spatial arrangement minimize electromagnetic interference (EMI) between adjacent high-speed data lanes. #### B. Contact Interface * **Plating:** The **R2** designation usually indicates a specific plating thickness (often 30µ" gold). This ensures low contact resistance and prevents oxidation over thousands of mating cycles. * **Contact Geometry:** Uses a "dual-beam" or "box" contact design to ensure constant pressure even under vibration. #### C. Power Management The **C4** code typically relates to the pin configuration (e.g., 4 power circuits). * **Thermal Dissipation:** The pins are thickened to handle higher current density without excessive heat buildup, preventing damage to the PCB (Printed Circuit Board) traces. --- ### 3. Suffix Meaning (General Industry Standard) While specific to the manufacturer (likely JPT, Molex, or a specialized industrial brand), the nomenclature generally follows this logic: * **M2:** Series identifier (Metric 2mm pitch or specific mechanical footprint). * **PHS:** Power/High-Speed Hybrid series. * **C4:** 4-circuit configuration or specific mechanical keying. * **R2:** Revision 2 or RoHS 2 compliance. * **CE:** European Conformity (meets safety, health, and environmental protection standards). --- ### 4. Typical Applications * **Blade Servers:** Connecting power and data from a backplane to a server blade. * **Industrial PLC:** Interfacing modular I/O units. * **Network Switches:** High-speed data throughput between line cards.
