### 2. Functional Electronic Components
Within this connector assembly, several "parts" or design elements ensure electrical integrity:
* **Contacts (Pins/Receptacles):** Made of copper alloy. They are precision-engineered to maintain a low contact resistance (typically < 30mΩ).
* **Housing (Insulator):** High-temperature thermoplastic (e.g., LCP - Liquid Crystal Polymer). This material prevents electrical arcing between pins and withstands reflow soldering temperatures.
* **Solder Tails:** Designed for SMT (Surface Mount Technology) or through-hole mounting to the PCB.
* **Alignment Pegs:** Plastic or metal posts that ensure the connector is perfectly centered on the PCB pads before soldering.

### 3. Application Use Cases
This specific connector is often found in "System-on-Module" (SoM) applications or "Carrier Board" designs.
1. **High-Speed Data:** Capable of handling differential signals for PCIe, SATA, or Ethernet protocols.
2. **Power Distribution:** Some pins can be grouped to carry low-to-medium current to the daughterboard.
3. **Signal Integrity:** The "R2" revision usually indicates an impedance-controlled design (often 100 Ohms) to minimize signal reflection in high-frequency circuits.
