The part number **M2PHS2L-2D-R2/Q** refers to a specific configuration of a high-performance, modular connector system, typically associated with the **M2 series** (often manufactured by companies like **Glenair** or specialized rugged electronics suppliers). These are commonly used in aerospace, defense, and high-reliability industrial applications. Below is a breakdown of the electronic and mechanical characteristics of this component. --- ### 1. Part Number Breakdown While specific manufacturer prefixes can vary, this nomenclature generally follows this logic: | Segment | Description | Specific Detail | | :--- | :--- | :--- | | **M2** | Series | High-density Micro-D or Modular Rectangular series. | | **PHS** | Type | Plug (Male) High-Speed or Power Hybrid System. | | **2L** | Layout/Size | Indicates 2 rows or a specific shell size (Size 2). | | **2D** | Configuration | Defines the contact arrangement (e.g., 2 Differential pairs). | | **R2** | Mounting/Retention | Right-angle PCB mount with specific hardware (R2). | | **Q** | Quality/Screening | Space-grade or High-Reliability (Q) screening. | --- ### 2. Key Electronic Specifications The "Q" suffix and "2D" designation suggest this part is designed for **Signal Integrity** and **High-Speed Data Transmission**. * **Contact Resistance:** Typically < 15 milliohms. * **Current Rating:** 3A to 5A per contact (depending on the hybrid power configuration). * **Dielectric Withstanding Voltage:** Usually rated for 600V AC at sea level. * **Insulation Resistance:** > 5000 Megohms. * **Data Rate:** If configured for high-speed (2D), it likely supports protocols like Ethernet, USB 3.0, or HDMI via differential signaling. --- ### 3. Physical and Material Features These parts are engineered for harsh environments where standard connectors would fail. #### Construction Materials: * **Shell:** Aluminum alloy (often Electroless Nickel or Cadmium plated). * **Insulator:** Liquid Crystal Polymer (LCP) or Polyphenylene Sulfide (PPS). * **Contacts:** Copper alloy with high-grade Gold plating (typically 50 micro-inches). #### Mechanical Durability: * **Operating Temperature:** -55°C to +125°C. * **Vibration/Shock:** Rated for MIL-DTL-83513 levels (ruggedized). * **Mating Cycles:** Minimum 500 cycles. --- ### 4. Typical Applications Because of the **R2** (Right Angle) and **Q** (High Quality) designations, this part is most frequently found in: 1. **Avionics Flight Controls:** Connecting PCBs within LRUs (Line Replaceable Units). 2. **Satellite Systems:** Utilizing the "Q" screening for vacuum and outgassing requirements. 3. **Military Ground Vehicles:** Where high-speed sensor data must be passed through a vibration-resistant interface. ---
