The **M2UDS2-14-R2** is a specific electronic component belonging to the **M2 series** of micro-miniature, high-performance connectors, typically used in high-density board-to-board or cable-to-board applications. Below is a detailed breakdown of its electronic and mechanical parts. ### 1. General Specifications | Feature | Description | | :--- | :--- | | **Component Type** | Connector (usually Header or Receptacle) | | **Series** | M2 Series (Micro-miniature) | | **Number of Positions** | 14 Pins | | **Rows** | Dual Row (indicated by "2") | | **Mounting Type** | Surface Mount (SMT) | | **Pitch** | Typically 1.0mm or 2.0mm (standard for M2 series) | --- ### 2. Key Electronic Parts and Materials The performance of the M2UDS2-14-R2 is defined by the quality of its internal contacts and housing materials: #### A. Contact Pins * **Material:** Usually made of **Phosphor Bronze** or **Beryllium Copper** for high conductivity and elasticity. * **Plating:** Typically features **Gold plating** over Nickel. Gold prevents oxidation and ensures low contact resistance, which is critical for low-voltage signal integrity. * **Current Rating:** Usually rated for 1A to 2A per contact depending on the specific environmental temperature. #### B. Insulator Body (Housing) * **Material:** High-temperature thermoplastic (e.g., **LCP - Liquid Crystal Polymer** or **Nylon 6T/9T**). * **Purpose:** Provides structural integrity and electrical isolation between the 14 pins. * **Heat Resistance:** Designed to withstand **Reflow Soldering** temperatures (up to 260°C). #### C. Mounting Interface * **SMT Leads:** The "leads" are the parts that touch the PCB pads. These are often "Gull-wing" shaped to provide a strong solder fillet and allow for visual inspection. --- ### 3. Application Use Cases Because of its small footprint and 14-pin configuration, this part is commonly found in: * **Handheld Electronics:** Tablets, smartphones, and medical devices. * **Industrial Modules:** Sensor interfaces and control boards. * **Automotive Systems:** In-car infotainment or camera modules where space is limited. --- ### 4. Part Number Breakdown (Typical) While naming conventions can vary slightly by manufacturer, the code usually breaks down as follows: * **M2:** Series identifier (Micro 2.0 or similar). * **UDS:** Universal Dual-row Surface-mount. * **2:** Dual row configuration. * **14:** Total number of circuits (pins). * **R2:** Packaging/Revision code (often indicates "Tape and Reel" for automated assembly).
