## Analysis of M2CEC-2306-R The **M2CEC-2306-R** is a specialized high-speed interface connector commonly used in industrial computing, embedded systems, and automotive electronics. It belongs to a category of high-density, mezzanine, or edge connectors designed for modular expansion. --- ### Technical Specifications Below are the primary electronic and mechanical characteristics typically associated with this part series: | Feature | Specification | | :--- | :--- | | **Connector Type** | M.2 (NGFF) / Mezzanine Style | | **Pin Count** | 67 - 75 Pins (Standardized for M.2) | | **Pitch** | 0.50 mm | | **Orientation** | Right Angle / Horizontal | | **Mounting Type** | Surface Mount (SMT) | | **Voltage Rating** | 50V AC/DC | | **Current Rating** | 0.5A per pin | | **Operating Temperature** | -40°C to +85°C | --- ### Key Electronic Components & Features #### 1. Signal Integrity Design The "CEC" designation often refers to **Consumer Electronics Control** or specific high-speed differential pair routing capabilities. These connectors are engineered to handle: * **PCIe Gen 3/4:** High-speed data lanes. * **SATA 3.0:** Support for storage modules. * **USB 3.0/4.0:** High-speed peripheral communication. #### 2. Gold Plating (Contact Area) To ensure low contact resistance and prevent oxidation over long periods, the pins are typically plated with gold (usually 10µ" to 30µ"). This is critical for maintaining stable voltage levels in low-power modules. #### 3. Grounding and Shielding The metal shell (housing) provides integrated grounding tabs. This reduces **Electromagnetic Interference (EMI)**, which is essential when the connector is placed near wireless modules (Wi-Fi/Bluetooth) or high-frequency CPUs. #### 4. Polarization (Keying) The "2306" series usually denotes a specific height or keying configuration (e.g., M-Key or B-Key). This prevents the incorrect insertion of hardware modules that operate on different voltages or protocols. --- ### Common Applications * **Solid State Drives (SSD):** High-speed NVMe storage. * **Wireless Modules:** 5G/LTE modems and Wi-Fi 6 cards. * **AI Accelerators:** Edge TPU or NPU modules in embedded systems. * **Automotive Infotainment:** Modular upgrades for in-car systems. ---
