The **M2REB-SA14-R** is a specific electronic component, typically categorized as a high-speed, high-density connector, often associated with memory or expansion interface standards (such as M.2 or similar card-edge form factors). Below is a detailed breakdown of its electronic parts, specifications, and design features. --- ### 1. General Specifications This part is a **Card Edge Connector** designed for surface mount technology (SMT). It is commonly used in industrial and consumer electronics for modular component integration. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Often JAE (Japan Aviation Electronics) or similar specialized vendors | | **Pitch** | 0.5 mm (Standard for high-density M.2/NGFF style) | | **Pin Count** | 14 Positions (SA14 designation) | | **Mounting Type** | Surface Mount (SMT) / Right Angle | | **Plating** | Gold over Nickel (standard for high-frequency signals) | | **Keying** | Specific mechanical key (likely "A" or "E" key depending on exact variant) | --- ### 2. Key Electronic Components & Construction The connector is comprised of several critical materials and design elements that ensure signal integrity: #### A. Contact Material * **Base Metal:** Usually Copper Alloy for excellent conductivity and flexibility. * **Plating:** Gold plating on the contact area to prevent oxidation and ensure low contact resistance over multiple mating cycles. #### B. Housing (Insulator) * **Material:** High-temperature Thermoplastic (LCP - Liquid Crystal Polymer). * **Purpose:** To withstand reflow soldering temperatures (up to 260°C) and provide electrical isolation between the 14 pins. #### C. Solder Tabs (Hold-downs) * Located at the sides of the connector, these metal tabs are soldered to the PCB ground plane to provide mechanical stability and strain relief, preventing the connector from being ripped off the board during card insertion. --- ### 3. Electrical Performance Because this part is designed for high-speed data transfer, its electronic characteristics are tightly controlled: * **Current Rating:** Typically 0.5A per pin. * **Voltage Rating:** 50V AC/DC. * **Insulation Resistance:** 500MΩ minimum. * **Dielectric Withstanding Voltage:** 300V AC for 1 minute. * **Contact Resistance:** Max 50mΩ (initial). --- ### 4. Typical Applications The "SA14" configuration is often found in: 1. **Wireless Modules:** Small form factor Wi-Fi or Bluetooth cards. 2. **Sensors:** Modular industrial sensors requiring a pluggable interface. 3. **IoT Devices:** Where space is limited and high-speed signal integrity is required. ---
