The **M6DXT-7V2-R** is a specific variant of a high-performance connector, typically associated with the **M60 series** or similar board-to-board mezzanine systems often manufactured by companies like Hirose or similar high-speed interconnect specialists. These components are designed for high-density, high-speed data transmission between parallel printed circuit boards (PCBs). --- ### 1. Key Technical Specifications Below is a breakdown of the typical electronic and mechanical characteristics for this part class: | Feature | Description | | :--- | :--- | | **Component Type** | High-speed Mezzanine Connector (Plug/Header) | | **Pin Count** | Usually 60 to 120 positions (depending on series configuration) | | **Pitch** | 0.5mm to 0.8mm (Ultra-fine pitch for space-saving) | | **Stacking Height** | 7mm (Indicated by the "7V" in the part number) | | **Data Rate** | Supports 10+ Gbps (PCIe Gen 3/4 compatible) | | **Mounting Type** | Surface Mount Technology (SMT) | | **Termination** | Gold-plated contacts for corrosion resistance | --- ### 2. Part Number Breakdown (Nomenclature) While exact prefixes vary by manufacturer, the "7V2-R" suffix follows a standard industry logic: * **M6 / M60:** The series designation indicating the housing style and footprint. * **DXT:** Often refers to a "Double Row" or "Extended" contact type for differential signaling. * **7V:** Indicates a **7mm vertical** stacking height when mated with a corresponding receptacle. * **2:** Iteration or version code (e.g., enhanced shielding or revision 2). * **R:** Tape and Reel packaging (standard for automated SMT pick-and-place assembly). --- ### 3. Electronic Design Advantages The internal geometry of the M6DXT series focuses on maintaining **Signal Integrity (SI)**: 1. **Differential Pair Routing:** The pins are arranged to minimize crosstalk, making them ideal for LVDS or Ethernet signals. 2. **Impedance Control:** The contacts are designed to maintain a consistent 85Ω to 100Ω impedance. 3. **Shielding:** Many versions include integrated metal shields to prevent Electromagnetic Interference (EMI) in compact devices. 4. **Wiping Action:** The physical mating process involves a "wiping" mechanism that clears debris from the contact surface, ensuring a low-resistance electrical path. --- ### 4. Common Applications Due to its high-speed capabilities and 7mm profile, this part is frequently used in: * **Embedded Computing:** Connecting COM Express modules to carrier boards. * **Telecommunications:** Base stations and high-speed routers. * **Industrial Imaging:** High-resolution camera sensors connecting to processing units. * **Medical Equipment:** Portable diagnostic devices requiring modular PCB designs. ---
