The **M2AS1-5222-R2/CE** is a specialized electronic component, specifically a **Micro-Coaxial Cable Assembly** (often referred to as an I-PEX or LVDS cable) commonly used in high-speed data transmission for displays, medical equipment, and telecommunications. Below is a breakdown of its technical specifications and electronic properties. --- ### 1. General Specifications | Feature | Details | | :--- | :--- | | **Component Type** | Micro-Coaxial Cable Assembly | | **Pitch** | Typically 0.5mm or 0.4mm (standard for M2 series) | | **Connector Brand** | Likely I-PEX (Caberline/Evac series compatible) | | **Data Rate** | Optimized for high-speed differential signaling (e.g., eDP, LVDS) | | **Compliance** | RoHS, CE certified | --- ### 2. Key Electronic Parts & Construction The assembly consists of several critical sub-components that ensure signal integrity: #### A. The Micro-Coaxial Wire * **Conductor:** Usually silver-plated or tin-plated copper wire (AWG 36 to AWG 44). * **Dielectric:** A thin layer of FEP (Fluorinated Ethylene Propylene) providing low capacitance. * **Shielding:** A spiral or braided copper shield that prevents EMI (Electromagnetic Interference). #### B. The Connector Interface (M2AS1) * **Contacts:** Gold-plated copper alloy pins to prevent oxidation and ensure low contact resistance. * **Housing:** LCP (Liquid Crystal Polymer) or high-temperature plastic to withstand SMT (Surface Mount Technology) reflow temperatures. * **Grounding Bar:** A metal shell that provides 360-degree shielding and mechanical strain relief. #### C. The PCB/Substrate Interface * The "R2" designation often refers to a specific revision or layout orientation of the pin-out on the internal PCB within the connector head, ensuring impedance matching (typically 100 ohms for differential pairs). --- ### 3. Application Areas Because of its high-density design and shielding capabilities, this part is used in: 1. **Notebook/Tablet Displays:** Connecting the motherboard to the LCD/OLED panel (eDP - Embedded DisplayPort). 2. **Medical Imaging:** Used in ultrasound probes or endoscopes where thin, flexible, and shielded cables are required. 3. **Drones/Robotics:** Connecting high-resolution cameras to the central processing unit. --- ### 4. Part Number Breakdown (Interpretation) * **M2AS1:** The series/family of the connector (Micro-axial 2nd generation). * **5222:** Often denotes the pin count or specific cable length (e.g., 22 pins or a 220mm length variant). * **R2:** Revision 2; indicates an update in materials or pin configuration. * **CE:** Compliance marking for European safety, health, and environmental protection standards.
