The **M2CEC-12001-R** is a specific part number belonging to the **M2CEC Series** of high-density connectors, typically manufactured by companies like **Yamaichi Electronics**. These components are specifically designed for high-speed data transmission and are commonly used in automotive and telecommunications hardware. --- ### 1. Technical Specifications The M2CEC series is characterized by its compact form factor and its ability to handle high-frequency signals. | Feature | Specification | |:---|:---| | **Connector Type** | Board-to-Board / High-Speed Interface | | **Number of Pins** | Varies by sub-model (Commonly high-density) | | **Pitch** | Typically 0.5mm to 1.0mm | | **Data Rate** | Optimized for PCIe, Ethernet, and LVDS signals | | **Mounting Type** | Surface Mount (SMT) or Through-Hole (depending on R/L suffix) | | **Plating** | Gold over Nickel (Standard for signal integrity) | --- ### 2. Key Electronic Characteristics These parts are engineered to minimize signal loss and electromagnetic interference (EMI). * **Impedance Matching:** Designed to maintain 85Ω or 100Ω differential impedance, which is critical for preventing signal reflections in high-speed circuits. * **Thermal Durability:** Often rated for automotive temperature grades (e.g., -40°C to +105°C), ensuring stability in harsh environments. * **EMI Shielding:** The metal housing (if present on the specific "R" variant) acts as a ground plane to shield sensitive data lines from external noise. * **Mechanical Reliability:** Features high mating cycle durability and vibration resistance, making it suitable for In-Vehicle Infotainment (IVI) systems. --- ### 3. Application Use-Cases The M2CEC-12001-R is typically found in the following electronic assemblies: 1. **Automotive Computing:** Connecting Central Gateway modules to Infotainment screens. 2. **ADAS Systems:** Linking camera sensors to the processing unit where high bandwidth is required. 3. **Industrial Servers:** Used in daughtercard-to-motherboard connections for localized data processing. --- ### 4. Part Number Breakdown (General Pattern) While manufacturers have proprietary codes, the suffix often indicates packaging or orientation: * **M2CEC:** Series Name. * **12001:** Specific pin configuration or internal design revision. * **-R:** Generally stands for **"Tape & Reel"** packaging for automated pick-and-place assembly, or **"Right Angle"** orientation.
