The **M2PHS2L-CD-R** belongs to a specific category of mechanical and electronic hardware components, typically identified as a **high-precision, self-clinching micro-pin** or specialized fastener used in dense electronic PCB (Printed Circuit Board) assemblies. Below is a detailed breakdown of its electronic and physical characteristics. --- ### 1. Component Overview This part is a **Self-Clinching Pin** designed for permanent installation into thin metal sheets or PCB substrates. It acts as a guide pin or a pivot point for sub-assemblies. | Feature | Specification Details | | :--- | :--- | | **Type** | Micro-Clinching Pin | | **Mounting Style** | Press-fit / Self-clinching | | **Material** | Usually Stainless Steel or Heat-treated Carbon Steel | | **Plating** | Clear over Zinc or Passivated (RoHS compliant) | | **Application** | Handheld electronics, wearable tech, and compact circuitry | --- ### 2. Breakdown of the Part Number (M2PHS2L-CD-R) The nomenclature can be broken down based on industry standards (often used by manufacturers like PEM or similar hardware specialists): * **M2**: Refers to the metric thread size or diameter (2.0mm). * **PHS**: Indicates the material series (often Stainless Steel for corrosion resistance in electronics). * **2L**: Specifies the length or the shank height (the portion extending from the board). * **CD**: Refers to the head style or a specific "Conical" or "Displace" design for flush mounting. * **R**: Generally stands for "Reel" packaging, indicating the part is supplied on a tape-and-reel for automated SMT (Surface Mount Technology) pick-and-place machines. --- ### 3. Key Electronic & Mechanical Functions #### A. Electrical Conductivity While primarily a mechanical fastener, these pins are often plated with conductive materials (like Tin or Zinc). This allows them to: * Act as an **Electrical Grounding** point between a PCB and a metal chassis. * Serve as a **Test Point** for automated probes during the QA process. #### B. Precision Alignment In multi-layered electronic stacks (like smartphones), these pins ensure that the LCD frame or the battery housing aligns perfectly with the motherboard. #### C. SMT Integration The **"-R" (Reel)** suffix is crucial for electronics manufacturing. It means the parts are compatible with: * **Vacuum Nozzles:** Picked up by automated assembly robots. * **Reflow Ovens:** Designed to withstand high soldering temperatures if integrated into a solder-paste process. --- ### 4. Technical Comparison | Metric | M2PHS (Stainless) | M2PH (Carbon Steel) | | :--- | :--- | :--- | | **Corrosion Resistance** | High | Moderate | | **Conductivity** | Good | Excellent (if plated) | | **Magnetic Property** | Non-magnetic (usually) | Magnetic | | **Hardness** | High | Very High | ---
