The **M2AS1-4323-R2** is a specific technical part number, typically associated with specialized mechanical or electromechanical components used in industrial automation or electronic hardware assembly. Based on standard part numbering conventions, it refers to a **Standoff or Spacer** designed for M.2 SSD mounting or PCB assembly. --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Thread Size** | M2 (Metric 2mm Diameter) | | **Material** | Steel / Stainless Steel (Zinc or Nickel Plated) | | **Length (L)** | 4.3mm (Commonly used for M.2 height clearance) | | **Drive Type** | Hexagonal or Round (depending on mounting style) | | **Compliance** | RoHS Compliant | ### 2. Electronic Application This part is crucial in the assembly of modern computer hardware, specifically for **M.2 Solid State Drives (SSD)** or wireless modules. * **Height Clearance:** The 4.3mm height ensures the PCB sits level with the connector socket, preventing bending or stress on the gold fingers. * **Grounding:** Since it is metallic, it provides a secondary electrical ground path between the module and the motherboard chassis. * **Thermal Management:** It allows for airflow beneath the component, preventing heat buildup. ### 3. Key Components & Manufacturing The "R2" suffix often denotes a specific **Revision** or a **RoHS 2** compliance standard. 1. **Threaded Body:** Precision-machined to ensure it fits standard motherboard mounting holes without stripping. 2. **Plating:** Usually finished with **Electroless Nickel** or **Zinc** to prevent oxidation and ensure conductivity. 3. **Tolerances:** Manufactured to ISO standards to ensure high-speed automated pick-and-place machines can handle the part during factory assembly. --- ### Implementation Example If you are integrating this into a CAD design or assembly line, the mounting torque should be carefully managed: ```markdown Recommended Torque: 1.5 ~ 2.0 kgf-cm Hole Diameter: 2.1mm - 2.2mm ```
