The part number **M2REB-S54-R2/N** typically refers to a high-density, high-speed connector, most commonly associated with **JAE (Japan Aviation Electronics)** or similar specialized electronic component manufacturers. This specific series is often used in automotive or industrial applications requiring robust signal integrity. ### 1. Component Specifications The following table outlines the technical characteristics generally associated with this part series: | Feature | Description | | :--- | :--- | | **Connector Type** | Board-to-Board / High-speed transmission | | **Number of Positions** | 54 Pins | | **Mounting Type** | Surface Mount (SMT) / Right Angle | | **Pitch** | Typically 0.5mm or 0.8mm (Series dependent) | | **Termination** | Solder | | **Material** | High-temperature thermoplastic (LCP) | | **Contact Plating** | Gold over Nickel | --- ### 2. Breakdown of Part Numbering While internal codes vary by manufacturer, the breakdown for this specific nomenclature usually follows this logic: * **M2REB**: The series identifier (often indicating a shielded, high-speed interface). * **S**: Indicates the Gender (typically **S**ocket/Female). * **54**: Indicates the **Pin Count** (54 positions). * **R2**: Refers to the physical orientation or packaging (e.g., Right Angle, Reel Type 2). * **SLASHN (/N)**: Usually denotes a specific revision, a "No-Lead" (RoHS compliant) status, or a specialized plating variant. --- ### 3. Key Electronic Characteristics #### Signal Integrity These connectors are designed to handle **LVDS** (Low-Voltage Differential Signaling) and **PCIe** protocols. They feature impedance control to minimize signal reflection and crosstalk at high frequencies. #### Environmental Durability * **Vibration Resistance:** Designed for automotive environments where constant mechanical stress is present. * **Thermal Range:** Usually rated for operation between **-40°C to +105°C**. * **Shielding:** Many "M2" series connectors include an integrated metal shell to provide EMI/EMC protection, crucial for sensitive communication modules. --- ### 4. Typical Applications 1. **Automotive Infotainment:** Connecting display panels to the Head Unit. 2. **ADAS Modules:** Interfacing cameras or radar sensors with processing boards. 3. **Industrial Computing:** Compact PLC modules or high-speed data acquisition cards.
