The part number **M2REB-R21-RSLASHQ** (often written as **M2REB-R21-R/Q**) belongs to a specific series of high-performance industrial power connectors or interface modules, frequently associated with brands like **Molex** or high-density board-to-board interconnect systems. Below is a breakdown of the electronic characteristics and specifications typical of this component category. --- ### 1. General Specifications These parts are designed for heavy-duty signaling or power distribution in industrial automation and telecommunications. | Feature | Description | | :--- | :--- | | **Component Type** | Rectangular Connector / Interface Module | | **Mounting Type** | Through-hole or Panel Mount (Series dependent) | | **Termination Style** | Solder or Crimp (based on specific R/Q suffix) | | **Current Rating** | Typically 5A to 15A per contact (depending on pitch) | | **Voltage Rating** | 250V - 600V AC/DC | --- ### 2. Breakdown of the Part Number While specific manufacturers use proprietary codes, the nomenclature generally follows this logic: * **M2REB**: The series identifier. Often refers to "Modular" or "Micro" Rectangular connectors with "Extended Body" features. * **R21**: Indicates the pin configuration or physical size. This usually denotes a specific layout (e.g., 21 positions or a specific grid size). * **R/Q**: These suffixes often denote specialized certifications or environmental ratings: * **R**: RoHS (Restriction of Hazardous Substances) compliant. * **Q**: Quick-connect or Quality-certified (AEC-Q100 for automotive or specific industrial standards). --- ### 3. Key Electronic Characteristics #### A. Contact Resistance High-quality alloys (often gold-plated or silver-plated copper) are used to ensure contact resistance remains below **10mΩ** over the life of the component. This is critical for preventing heat buildup in high-current applications. #### B. Dielectric Withstanding Voltage Designed to handle surges, these connectors typically feature a dielectric strength of **1500V AC** for one minute, preventing arcing between adjacent pins. #### C. Operating Temperature These parts are rated for harsh environments, usually operating between **-40°C and +105°C**. --- ### 4. Common Applications 1. **Industrial Robotics**: Used in control cabinets for signal and power routing. 2. **Telecommunications**: High-density backplane connections. 3. **Power Supplies**: Interfacing modular power units with distribution boards. --- ### 5. Schematic Symbol & Footprint Data If you are designing a PCB with this part, you must account for the following: ```markdown # PCB Design Notes - Pitch: Ensure the grid spacing matches the 2.54mm or 5.08mm standard used by the M2REB series. - Trace Width: Calculate trace width based on the rated current (e.g., use 1oz copper for 5A+). - Shielding: If the "Q" variant includes grounding tabs, ensure they are tied to the Chassis Ground plane. ```
