The part number **M2REB-R23-M2/N** corresponds to a specific configuration within the **M2 series** of high-density, multi-pin rectangular connectors, typically manufactured by companies like **Positronic** or similar aerospace-grade connector specialists. These connectors are designed for high-reliability applications, including military, aerospace, and medical electronics. --- ## 1. Technical Specifications Breakdown The alphanumeric code identifies the physical and electrical characteristics of the unit: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Series** | M2 | High-density rectangular series. | | **Contact Gender** | REB | Receptacle (Female) with specific mounting options. | | **Contact Count** | 23 | Total number of signal/power pins in the housing. | | **Mounting Style** | M2 | Metric thread hardware or specific PCB mount legs. | | **Plating/Finish** | /N | Non-magnetic or specific Nickel/Gold plating finish. | --- ## 2. Key Electronic Components ### A. Contacts and Pins * **Material:** Usually high-conductivity Copper Alloy. * **Plating:** Gold plating (typically 0.76 µm or 30 µin) over Nickel is standard to prevent oxidation and ensure low contact resistance over thousands of mating cycles. * **Current Rating:** Typically rated for **5 to 7.5 Amps** per contact, depending on the wire gauge used. ### B. Insulator Body * **Material:** Glass-filled Diallyl Phthalate (DAP) or Polyester. * **Dielectric Strength:** Capable of withstanding high voltages (often >1000V RMS at sea level) without arcing between pins. * **Insulation Resistance:** Usually >5,000 Megohms. ### C. Environmental Shielding * **Non-Magnetic Properties:** The `/N` suffix often denotes a non-magnetic version, essential for medical imaging (MRI) or satellite applications where electromagnetic interference must be minimized. --- ## 3. Physical Layout & Mechanical Features * **Polarization:** The trapezoidal "D" shape of the shell ensures that the connector can only be mated in the correct orientation. * **Vibration Resistance:** Designed to meet MIL-DTL-28748 standards, ensuring electrical continuity even under extreme mechanical stress. * **Termination:** Usually supports **Crimp** or **Solder Cup** terminations, though "R23" versions are often configured for right-angle PCB mounting. --- ## 4. Common Applications 1. **Avionics:** Flight control systems where space is limited but pin density must be high. 2. **Medical:** Diagnostic equipment requiring non-magnetic components. 3. **Industrial Automation:** Heavy-duty sensors and controllers requiring secure, multi-path connections.
