The **M2PHS2H-A1-R2/Q** is a specific part number typically associated with high-density, multi-pin electrical connectors, often used in aerospace, industrial automation, or telecommunications hardware. Based on standard nomenclature for this series, here is the breakdown of its electronic and physical specifications. --- ## 1. Technical Specifications | Parameter | Details | | :--- | :--- | | **Component Type** | High-density Board-to-Board / Wire-to-Board Connector | | **Pitch** | 2.00 mm (Standard for M2 series) | | **Mounting Type** | Through-hole or Surface Mount (depending on suffix) | | **Contact Material** | Phosphor Bronze or Copper Alloy | | **Plating** | Gold (Au) over Nickel (Ni) for high conductivity | | **Current Rating** | 1A - 2A per contact | | **Voltage Rating** | 125V - 250V AC/DC | --- ## 2. Part Number Breakdown While manufacturers vary, the alphanumeric code generally follows this logic: * **M2**: Series designation (likely referring to the 2.0mm metric pitch). * **PH**: Pin Header (the male side of the connection). * **S2H**: Likely refers to a **S**hrouded, **2**-row, **H**orizontal (Right Angle) configuration. * **A1**: Specific version or revision of the plastic housing/insulator height. * **R2**: Refers to the packaging (e.g., Reel or Tube) or a specific plating thickness (e.g., 20u" Gold). * **Q**: Quality assurance or specific material compliance (e.g., Halogen-free). --- ## 3. Key Electronic Characteristics ### Signal Integrity These connectors are designed for low-resistance connections. The gold plating ensures that even in humid or high-vibration environments, the electrical contact remains stable without oxidation. ### Thermal Durability The housing is typically made of high-temperature thermoplastic (like LCP or PBT), allowing the part to withstand: * **Operating Temp:** -40°C to +105°C. * **Soldering Temp:** Compatible with lead-free reflow profiles (up to 260°C). ### Mechanical Keying The "Shrouded" (PHS) nature of the part prevents "mismating." It ensures that the cable or daughterboard can only be inserted in the correct orientation, protecting sensitive pins from bending. --- ## 4. Common Applications * **Embedded Systems:** Connecting SBCs (Single Board Computers) to peripheral shields. * **Industrial Controls:** Internal signal routing for PLC units. * **Medical Electronics:** Used in diagnostic equipment where high-density, reliable connections are required.
