The **M2REB-RBB-R/C** is a specific part number typically associated with the **M2 series** of high-density, multi-pin rectangular connectors, often manufactured by companies like **Positronic** or similar aerospace/industrial component providers. These connectors are engineered for high-reliability environments. --- ### 1. Technical Specifications Overview This component belongs to the sub-miniature connector family. Below are the typical electronic and physical attributes associated with this series: | Feature | Specification | | :--- | :--- | | **Connector Type** | High-density Rectangular Connector | | **Contact Gender** | Female (Receptacle) | | **Termination Style** | Board Mount (Right Angle) | | **Pin Count** | High density (e.g., 26, 44, 62, or 78 positions depending on the shell size) | | **Contact Plating** | Gold over Nickel (standard for R/C high-reliability) | | **Housing Material** | Steel with Zinc or Cadmium plating (Environmental/Corrosion resistant) | --- ### 2. Part Number Breakdown (Typical) While specific manufacturers vary slightly, the nomenclature usually follows this logic: * **M2**: Series designation (High-density D-sub type). * **REB**: Refers to the mounting style or specific insert arrangement (often "Right Angle Board Mount"). * **RBB**: Indicates the hardware configuration (e.g., threaded spacers, lock-blocks, or board locks). * **R/C**: Stands for **RoHS Compliant**. This confirms the part does not contain lead, mercury, or other restricted hazardous substances. --- ### 3. Key Electronic Characteristics These parts are designed for low signal loss and high durability: 1. **Current Rating**: Generally rated for **5 Amperes** per contact. 2. **Dielectric Withstanding Voltage**: Typically tested up to **1000V AC** (RMS) at sea level. 3. **Insulation Resistance**: High resistance (typically **5 Gigaohms** minimum) to prevent leakage between adjacent pins. 4. **Contact Resistance**: Low milliohm range (usually **< 10 mΩ**) to ensure signal integrity. --- ### 4. Common Applications Due to the "R/C" (RoHS) certification and the high-density nature of the connector, it is used in: * **Aerospace & Defense**: Flight control systems and avionics. * **Industrial Automation**: PLCs and high-density control panels. * **Medical Electronics**: Imaging equipment and patient monitoring. * **Telecommunications**: Rack-mounted servers and switching gear. ---
