### Overview of M2CEC-1105-R The **M2CEC-1105-R** is a specialized electronic component, typically categorized as a high-density, high-speed connector, often used in communication and networking hardware. It is part of the **M2CEC series**, which is designed for board-to-board or cable-to-board applications requiring robust signal integrity. --- ### Technical Specifications and Features | Feature | Specification / Detail | | :--- | :--- | | **Component Type** | Connector / Header Assembly | | **Pitch** | Typically 0.5mm or 0.8mm (varies by sub-series) | | **Contact Material** | Copper Alloy with Selective Gold Plating | | **Insulation Material** | High-Temperature Thermoplastic (LCP) | | **Current Rating** | ~0.5A to 1.0A per pin | | **RoHS Compliance** | Yes (indicated by the "-R" suffix) | --- ### Detailed Electronic Characteristics #### 1. Signal Integrity The internal architecture of the M2CEC-1105-R is engineered to minimize **crosstalk** and **insertion loss**. This makes it suitable for high-frequency data transmission protocols like PCIe, SATA, or high-speed Ethernet interfaces. #### 2. Durability and Plating * **Gold Plating:** The contact points are usually plated with gold to prevent oxidation and ensure a low-resistance connection over hundreds of mating cycles. * **Mechanical Stability:** The "R" suffix often denotes "Receptacle" or "Right-angle" depending on the manufacturer's nomenclature, but in most cases, it signifies **RoHS compliance** (Lead-free). #### 3. Mounting Style This component is typically a **Surface Mount Technology (SMT)** part. It features "gull-wing" or "J-lead" pins that allow for automated pick-and-place assembly on a Printed Circuit Board (PCB). --- ### Common Applications * **Networking Gear:** Used in routers, switches, and server blade systems. * **Embedded Computing:** High-density board-to-board stacking in industrial PCs. * **Storage Systems:** Interfacing between controllers and backplanes. --- ### Comparison: M2CEC-1105-R vs. Standard Headers | Attribute | M2CEC-1105-R | Standard Pin Header | | :--- | :--- | :--- | | **Density** | High (Fine Pitch) | Low (2.54mm Pitch) | | **Shielding** | Often includes EMI shielding | No Shielding | | **Assembly** | SMT (Reflow) | Through-Hole or SMT |
