The **M2PHSL-13-R2** is a specific type of electronic connector, typically belonging to the family of high-density pin headers. This component is designed for Board-to-Board or Wire-to-Board connections in compact electronic assemblies. ### 1. Technical Specifications Overview The part number follows a standard nomenclature used by manufacturers (often associated with brands like Sullins or generic high-precision hardware). | Feature | Description | | :--- | :--- | | **Component Type** | Male Pin Header | | **Pitch** | 2.00mm (0.079 inches) | | **Number of Rows** | Dual Row (2 Rows) | | **Total Pins** | 26 Pins (13 positions per row) | | **Mounting Style** | Surface Mount (SMT) or Through-Hole (depending on specific R2 variant) | | **Contact Material** | Phosphor Bronze or Brass | | **Plating** | Gold Flash or Selective Gold | --- ### 2. Key Electronic Characteristics Understanding the electrical limitations of the M2PHSL series is critical for circuit design: * **Current Rating:** Typically **2.0A per contact**. This makes it suitable for signal transmission and low-power distribution. * **Insulation Resistance:** Usually rated at **1000MΩ Minimum**, ensuring minimal leakage between adjacent pins. * **Contact Resistance:** Roughly **20mΩ Maximum**, providing a stable, low-impedance connection. * **Dielectric Withstanding Voltage:** Generally **500V AC/minute**, which defines the breakdown voltage of the plastic housing. --- ### 3. Physical Construction and Materials The "R2" suffix often denotes a specific revision or packaging style (like Tape & Reel for automated assembly). 1. **Insulator:** High-Temperature Thermoplastic (often LCP or Nylon 6T). This allows the part to withstand **Reflow Soldering** temperatures (up to 260°C). 2. **Shrouding:** The "SL" in the part number often indicates a **Slim Line** or **Shrouded** design. Shrouding protects the pins from bending and ensures the mating connector can only be inserted in one orientation (Polarization). 3. **Gold Plating:** The pins are usually gold-plated to prevent oxidation and ensure high conductivity over many mating cycles. --- ### 4. Common Applications Due to its 2.0mm pitch (which is smaller than the standard 2.54mm/0.1" pitch), this part is used in space-constrained environments: * **Embedded Systems:** Connecting Raspberry Pi HATs or industrial SOMs (System on Modules). * **Consumer Electronics:** Internal connections in laptops, cameras, and handheld devices. * **Industrial Automation:** Linking PCB stacked layers in PLC controllers.
