The **M2REB-S5D-R** is a specific electronic component typically categorized as a **Surface Mount (SMT) Receptacle Connector**, often used in automotive or industrial high-speed data transmission applications. --- ### 1. Key Specifications Based on the part numbering convention (common for manufacturers like Rosenberger or similar high-frequency connector specialists), here are the technical specifications: | Feature | Description | | :--- | :--- | | **Component Type** | HSD (High-Speed Data) Connector / Receptacle | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Orientation** | Right Angle (Side Entry) | | **Coding** | Coding D (Usually identified by Bordeaux/Violet color) | | **Interface Type** | MATE-AX or similar Fakra-style high-speed interface | | **Impedance** | 100 $\Omega$ (Differential) | --- ### 2. Physical Construction The part is comprised of several critical sub-components that ensure electrical integrity and mechanical durability: * **Center Contacts:** Gold-plated copper alloy to ensure low contact resistance and high signal integrity. * **Insulator:** High-temperature engineering plastic (LCP or similar) capable of withstanding lead-free reflow soldering temperatures. * **Outer Shield (Housing):** Die-cast zinc or tin-plated brass to provide 360-degree EMI/EMC shielding. * **Solder Pins/Leads:** Designed for automated pick-and-place assembly on PCBs. --- ### 3. Electrical Performance This part is designed to handle high-frequency data protocols. Typical performance metrics include: 1. **Frequency Range:** DC to 6 GHz (or higher depending on specific series). 2. **Data Rate:** Capable of supporting LVDS, Ethernet (100Base-T1 / 1000Base-T1), and USB 2.0/3.0. 3. **Return Loss:** Typically $\leq -20$ dB up to 2 GHz. 4. **Insertion Loss:** Minimal signal degradation over high-speed links. --- ### 4. Applications The M2REB-S5D-R is primarily found in environments where vibration resistance and high data throughput are required: * **Automotive Infotainment:** Connecting head units to displays. * **ADAS (Advanced Driver Assistance Systems):** Routing camera feeds to processing units. * **Telematics:** High-speed communication modules. * **Industrial Automation:** High-resolution sensor data transmission. --- ### 5. Coding System (D-Coding) The "D" in the part number refers to the mechanical "keying." Connectors of this type use color-coded plastic housings to prevent incorrect mating: * **Coding D** is traditionally **Bordeaux Violet**. * It ensures that a Cable Plug with "D" coding can only be inserted into a Receptacle with "D" coding.
