The **M2AS1-5213-R2** is a specialized high-speed connector component, typically part of a mezzanine connector system used in telecommunications, data networking, and high-performance computing. It is designed to facilitate board-to-board connections with high signal integrity. --- ### Technical Specifications Below are the general electronic and mechanical characteristics associated with this part series: | Parameter | Specification (Typical) | | :--- | :--- | | **Connector Type** | Mezzanine / Board-to-Board | | **Pitch** | 1.27mm or 1.0mm (Series dependent) | | **Pin Count** | 52-Pin (Based on part numbering) | | **Mounting Type** | Surface Mount (SMT) | | **Contact Material** | Copper Alloy | | **Plating** | Gold over Nickel | | **Voltage Rating** | 125V AC/DC | | **Current Rating** | 1.0A - 1.5A per contact | --- ### Key Electronic Components & Features #### 1. Signal Integrity (SI) Design The "R2" designation often refers to a revision or a specific impedance rating. These parts are engineered to minimize: * **Crosstalk:** Reducing interference between adjacent signal pins. * **Insertion Loss:** Ensuring signal strength is maintained at high frequencies (multi-GHz range). #### 2. Contact Interface The internal electronic parts consist of precision-stamped contacts. The gold plating ensures a low-resistance electrical path and prevents oxidation, which is critical for low-voltage data signals. #### 3. High-Temperature Housing The body is made of high-temperature thermoplastic (e.g., LCP - Liquid Crystal Polymer). This allows the part to withstand the heat of lead-free reflow soldering processes without warping, maintaining the precise alignment of the 52 pins. #### 4. Alignment & Polarization The physical design includes electronic "keying" features. These ensure the boards are mated in the correct orientation, preventing short circuits that could damage the sensitive integrated circuits (ICs) on the connected PCBs. --- ### Typical Applications * **Networking Gear:** Switches and routers. * **Industrial PC:** Connecting CPU modules to carrier boards (COM Express style). * **Storage Systems:** High-speed data transfer between controller cards and backplanes.
