The **M2PHS2H-163-R/CE** is a specialized high-density electrical connector, typically belonging to a series of high-speed, high-reliability headers used in industrial automation, telecommunications, or specialized computing hardware. --- ### 1. Key Technical Specifications Based on the part number nomenclature common in the electronics industry, here are the primary electronic and physical characteristics: | Feature | Description | | :--- | :--- | | **Component Type** | High-density Pin Header (Male Connector) | | **Pitch** | Typically 2.0mm or 1.27mm (Common for "M2" series) | | **Configuration** | 163-pin (High density) | | **Mounting Type** | Through-hole (THT) or Surface Mount (SMT) depending on sub-series | | **Plating** | Selective Gold or Tin-Lead (Indicated by R/CE suffix) | | **Termination** | Right-angle or Straight (H usually denotes Horizontal/Right-angle) | --- ### 2. Breakdown of the Part Number Electronic part numbers are often codes that represent specific physical attributes: * **M2PH**: Series prefix, usually indicating a "Micro" or "Metric" High-density Header. * **S2H**: Denotes the housing style and orientation (likely **S**hrouded, **2** rows, **H**orizontal/Right-angle). * **163**: The pin count (163 positions). * **R/CE**: Environmental and plating compliance: * **R**: Often refers to RoHS Compliance. * **CE**: May refer to European Conformity or a specific plating thickness (e.g., Gold over Nickel). --- ### 3. Electrical Characteristics Connectors of this class are designed to handle specific signal integrity requirements: 1. **Current Rating:** Generally rated for 1A to 3A per pin, depending on the pitch and ambient temperature. 2. **Voltage Rating:** Typically rated between 125V and 250V AC/DC. 3. **Contact Resistance:** Low resistance (usually < 20mΩ) to ensure signal clarity in high-speed data transmission. 4. **Insulation Resistance:** Usually > 1000MΩ at 500V DC to prevent cross-talk between high-density pins. --- ### 4. Common Applications * **Backplane Interconnects:** Used to connect daughter cards to a main motherboard. * **Industrial Control Systems:** High-pin count connectors are used in PLCs and robotics for complex signal routing. * **Network Hardware:** Servers and switches requiring high-density I/O. ---
