The **M2CEC-15002-R** is a specific high-performance connector part, typically associated with high-speed data transmission and edge-card applications. Below is a detailed breakdown of its electronic characteristics and specifications. --- ## Technical Specifications | Parameter | Specification Details | | :--- | :--- | | **Part Number** | M2CEC-15002-R | | **Type** | Edge Card Connector (Mezzanine/PCIe style) | | **Pitch** | Typically 0.8mm or 1.0mm (standard for M2/mSATA series) | | **Mounting Type** | Surface Mount (SMT) / Right Angle | | **Contact Material** | Copper Alloy with Gold Plating | | **Termination** | Solder | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ## Key Electronic Components & Features ### 1. Contact Interface The connector uses high-conductivity copper alloy pins. The interface is usually plated with **Gold (Au)** over **Nickel (Ni)**. * **Purpose:** To prevent oxidation and ensure a low-resistance electrical path for high-frequency signals. ### 2. Signal Integrity (SI) Design As a high-speed connector, the internal geometry is designed to maintain: * **Impedance Control:** Usually matched to 85Ω or 100Ω to minimize signal reflections. * **Crosstalk Reduction:** Physical spacing and shielding between pins are optimized to prevent electromagnetic interference (EMI) between adjacent data lanes. ### 3. Thermal & Structural Housing The body is made of high-temperature thermoplastic (e.g., LCP - Liquid Crystal Polymer). * **Reflow Compatibility:** Designed to withstand the high heat of lead-free soldering ovens. * **Durability:** Rated for a specific number of mating cycles (insertion/extraction) without mechanical failure. --- ## Typical Applications The M2CEC series is frequently found in industrial and consumer computing environments: 1. **Storage Modules:** Connecting M.2 NVMe or SATA SSDs to motherboards. 2. **Wireless Modules:** Facilitating Wi-Fi or Bluetooth card connections in embedded systems. 3. **Industrial Controllers:** Used for modular expansion in PLC (Programmable Logic Controller) units. --- ### Mechanical Considerations * **Keying:** The physical "key" in the connector prevents the incorrect insertion of cards (e.g., preventing a B-key card from entering an M-key slot). * **Retention:** Often includes side latches or screw-down points to ensure the card remains seated under vibration.
