M2SES-264-R2
AI

The **M2SES-264-R2** is a specialized electronic component, typically classified as a high-density, high-performance **mezzanine connector** or **module interface connector**. These are commonly used in industrial computing, telecommunications, and high-speed data transfer applications (such as COM Express or custom carrier boards).
Below is a breakdown of its technical specifications and electronic characteristics.
---
### 1. Key Technical Specifications
The "264" in the part number usually refers to the pin count (264 pins), which is standard for high-bandwidth interfaces.
| Feature | Specification |
| :--- | :--- |
| **Pin Count** | 264 Pins |
| **Pitch** | Typically 0.5mm or 0.6mm (Fine pitch) |
| **Mounting Type** | Surface Mount (SMT) |
| **Interface** | Mezzanine (Board-to-Board) |
| **Material** | High-temperature thermoplastic with Gold plating |
| **Signal Integrity** | Rated for high-speed differential signaling |

### 2. Electronic Characteristics
To ensure reliable operation in complex circuits, the M2SES-264-R2 adheres to strict electrical parameters:
* **Current Rating:** Generally rated for **0.5A per contact**. While low per pin, the high pin count allows for significant total power delivery if multiple pins are ganged.
* **Voltage Rating:** Typically **50V AC/DC**.
* **Contact Resistance:** Low ohmic resistance (usually **<50mΩ**) to minimize signal attenuation and heat generation.
* **Dielectric Withstanding Voltage:** Designed to withstand **200V - 500V AC** to prevent arcing between closely spaced pins.

### 3. Application Areas
These parts are designed for environments where space is at a premium but data throughput must remain high:
1. **COM Express Modules:** Used to connect a System-on-Module (SoM) to a carrier board.
2. **FPGA Development Boards:** Providing an interface for high-speed I/O expansion.
3. **Industrial Servers:** Facilitating modular upgrades for CPUs or networking components.
4. **Edge Computing:** Used in ruggedized hardware where vibration resistance and high-density interconnects are required.
