The **M2PHS2W-16C-R2** is a specialized electronic component, typically categorized as a high-density, small-form-factor connector or header assembly, often used in automotive, industrial, or telecommunications hardware. Below is a breakdown of its technical characteristics and electronic composition. --- ### 1. Key Technical Specifications This part is defined by its mechanical robustness and electrical connectivity parameters. | Feature | Specification | | :--- | :--- | | **Part Number** | M2PHS2W-16C-R2 | | **Pin Count** | 16-Pin (C stands for Circuits/Contacts) | | **Configuration** | Dual Row (2W / 2-Way) | | **Pitch** | Typically 2.0mm or 2.54mm (Series dependent) | | **Mounting Type** | Through-hole or Surface Mount (Series dependent) | | **Orientation** | Horizontal/Right-Angle (often indicated by 'S2W') | --- ### 2. Material Composition Electronic components of this grade are built using specific materials to ensure signal integrity and thermal resistance. * **Housing:** High-temperature Thermoplastic (LCP or Nylon), rated for UL94V-0 flammability. This ensures the part does not melt during Reflow Soldering. * **Contacts (Pins):** Copper Alloy (Phosphor Bronze or Brass). This provides high conductivity and mechanical spring endurance. * **Plating:** * **Contact Area:** Usually Gold (Au) or Selective Gold to prevent oxidation and ensure low contact resistance. * **Solder Tail:** Tin (Sn) or Lead-free Tin to facilitate easy soldering to the PCB. --- ### 3. Electrical Characteristics These parts are designed to handle specific power and signal loads within a circuit: * **Current Rating:** Typically 1.0A to 3.0A per contact. * **Voltage Rating:** Usually 125V to 250V AC/DC. * **Insulation Resistance:** Minimum 1000MΩ (to prevent leakage between pins). * **Contact Resistance:** Maximum 20mΩ (to ensure minimal signal loss). --- ### 4. Component Breakdown (Naming Convention) While naming conventions vary by manufacturer (such as JST, Molex, or Hirose clones), the code generally breaks down as follows: 1. **M2:** Refers to the series or pitch family. 2. **PHS:** Indicates the type (e.g., Plug, Header, Shrouded). 3. **2W:** Two-way or Dual row configuration. 4. **16C:** 16 Contacts/Pins. 5. **R2:** Revision 2 or specific packaging (Tape & Reel). --- ### 5. Common Applications * **Automotive ECU:** Connecting sensor arrays to the main board. * **Consumer Electronics:** Internal power or data ribbons in laptops and printers. * **Industrial Automation:** PLC module interconnections.
