The **M2CEC-23004-R/Q** is a specific part number typically associated with **customized cable assemblies or board-to-board connectors**, often manufactured by companies like **Samtec** or similar precision interconnect firms. Based on the nomenclature, this part belongs to high-speed, high-density mezzanine connector systems used in telecommunications, networking, and industrial computing. --- ### 1. Component Overview The "M2CEC" series is generally categorized as a **High-Speed Mezzanine Interconnect**. These are designed to stack two PCBs (Printed Circuit Boards) parallel to each other while maintaining signal integrity at high data rates. | Feature | Specification Details | | :--- | :--- | | **Component Type** | Mezzanine Connector / High-Speed Cable Assembly | | **Data Rate Capabilities** | Often 28+ Gbps (depending on specific configuration) | | **Contact Material** | Phosphor Bronze or Copper Alloy with Gold Plating | | **Mounting Type** | Surface Mount (SMT) or Press-fit | | **Impedance** | Typically 50 $\Omega$ (Single-ended) or 100 $\Omega$ (Differential Pair) | --- ### 2. Breakdown of the Part Number While specific manufacturer codes vary, the breakdown generally follows this logic: * **M2CEC**: The series designation (High-speed internal connector). * **23004**: The specific pin count or geometric configuration (often indicates 23 positions or a specific length). * **-R**: Typically stands for **RoHS Compliant** (Lead-free). * **-Q**: Often indicates **Automotive Grade** (AEC-Q100/200) or a specific **Quality/Testing** standard. --- ### 3. Key Electronic Characteristics These parts are engineered to solve specific electrical engineering challenges: 1. **Crosstalk Reduction:** The internal structure uses shielding and optimized pin layouts to prevent interference between adjacent high-speed signal lines. 2. **Low Insertion Loss:** Designed to transmit signals over the connection with minimal power loss. 3. **Mechanical Reliability:** The "Q" designation suggests higher vibration resistance and thermal cycling durability, making it suitable for harsh environments. --- ### 4. Typical Applications These connectors are found in high-performance hardware where space is limited but data throughput is critical: * **Server Blades:** Connecting daughter cards to the main motherboard. * **FPGA Development Boards:** Connecting high-speed I/O expansion modules. * **Medical Imaging:** High-definition video data transfer within MRI or CT equipment. * **Automotive ADAS:** Connecting sensor processing units in autonomous driving systems.
