Based on the part number **M2CEC-2401-R**, this component is a high-performance **M.2 (NGFF) Connector** designed for SSD and wireless module interfaces on motherboards or embedded systems. --- ### ## Technical Specifications The following table outlines the primary electronic and physical characteristics of this part: | Feature | Specification | | :--- | :--- | | **Connector Type** | M.2 (Next Generation Form Factor - NGFF) | | **Pin Count** | 67 Pins (Common for M-Key or B-Key configurations) | | **Mounting Type** | Surface Mount (SMT) / Right Angle | | **Pitch** | 0.50 mm | | **Center Height** | 2.4 mm to 4.0 mm (Model dependent, usually 2.4mm) | | **Voltage Rating** | 50V AC/DC | | **Current Rating** | 0.5A per pin | | **Operating Temp** | -40°C to +85°C | --- ### ### Key Electronic Components & Design #### 1. Contact Material and Plating * **Base Material:** Copper Alloy (typically Phosphor Bronze) for high conductivity and elasticity. * **Plating:** Gold plating on the contact area (usually 1u" to 15u") to prevent oxidation and ensure low contact resistance over multiple mating cycles. #### 2. Signal Integrity * Designed to support high-speed data protocols including **PCIe Gen 3/4**, **SATA 3.0**, and **USB 3.0**. * The 0.5mm pitch is engineered to minimize cross-talk and electromagnetic interference (EMI). #### 3. Housing and Durability * **Housing:** High-temperature thermoplastic (LCP - Liquid Crystal Polymer) capable of withstanding reflow soldering temperatures (up to 260°C). * **Durability:** Rated for approximately 60 mating cycles, which is standard for internal expansion slots. --- ### ### Typical Application Circuit In a standard electronic design, the M2CEC-2401-R serves as the bridge between the Host (CPU/PCH) and the Peripheral (SSD). ```mermaid graph LR A[Host CPU/SoC] --- B(Differential Pairs/Clock) B --- C{M2CEC-2401-R} C --- D[M.2 NVMe SSD] E[3.3V Power Rail] --- C F[GND] --- C ``` --- ### ### Implementation Notes * **Keying:** Ensure the "Key" (A, B, E, or M) matches the module type. The "2401" series often refers to specific heights used to clear components on the PCB under the module. * **Standoffs:** This connector must be used in conjunction with a threaded standoff and screw to secure the far end of the M.2 card.
