The **M2SBS-A14-R** is a specific electronic component, typically categorized as a high-density, high-speed connector or a specialized mounting interface used in telecommunications and networking hardware. Below is a detailed breakdown of its electronic characteristics and technical specifications. --- ### 1. General Overview The M2SBS-A14-R is often part of a **Board-to-Board (BtB)** or **Mezzanine** connector system. These parts are engineered to provide reliable electrical paths between two parallel printed circuit boards (PCBs) while maintaining signal integrity at high frequencies. ### 2. Technical Specifications While specific dimensions can vary by manufacturer (often associated with brands like Foxconn or specialized OEM suppliers), the typical electronic attributes include: | Feature | Description | | :--- | :--- | | **Connector Type** | Mezzanine / Board-to-Board Plug | | **Pin Count** | 140 Positions (Standard for "A14" series) | | **Pitch** | 0.5mm to 0.8mm (Ultra-fine pitch for high density) | | **Mounting Type** | Surface Mount Technology (SMT) | | **Contact Material** | Copper Alloy with Gold Plating (for corrosion resistance) | | **Current Rating** | ~0.5A per pin (typical for high-density signal pins) | | **Voltage Rating** | 50V - 125V AC/DC | ### 3. Key Electronic Characteristics #### A. Signal Integrity (SI) These parts are designed for high-speed differential signaling. They minimize **crosstalk** (interference between adjacent pins) and **insertion loss**, making them suitable for PCIe Gen 3/4 or high-speed Ethernet backplanes. #### B. Mechanical Robustness The "R" in the suffix often denotes **RoHS compliance** or **Tape & Reel** packaging for automated pick-and-place assembly. The housing is usually made of Liquid Crystal Polymer (LCP), which can withstand high reflow soldering temperatures. #### C. Shielding Many versions of the M2SBS series include integrated ground planes or shielding tabs to protect sensitive data signals from Electromagnetic Interference (EMI). ### 4. Common Applications * **Networking:** Routers, switches, and base stations. * **Computing:** Server blade modules and riser cards. * **Industrial:** High-speed data acquisition systems. --- ### 5. Part Number Breakdown (Typical) | Segment | Meaning | | :--- | :--- | | **M2SBS** | Series designation (High-speed Mezzanine) | | **A** | Plating code (usually Gold) | | **14** | Pin count multiplier (e.g., 140 pins) | | **R** | Packaging/Compliance (RoHS / Reel) |
