Based on the model number **M2PHS2H-A4-R/N**, this component belongs to a series of high-speed, high-density board-to-board connectors, typically manufactured by companies like **Iriso Electronics**. These are designed for automotive and industrial applications where vibration resistance and high-speed data transmission are critical. --- ### Technical Specifications Overview Below is a breakdown of the typical electronic and mechanical characteristics for this specific part series: | Feature | Specification | |:---|:---| | **Component Type** | Floating Board-to-Board Connector | | **Pitch** | 0.5 mm | | **Number of Pins** | 40 Pins (Represented by "4" in the code sequence) | | **Orientation** | Right-Angle / Horizontal (R) | | **Mounting Type** | Surface Mount (SMT) | | **Data Rate** | Up to 8 Gbps+ (High-speed transmission support) | | **Floating Range** | ±0.5 mm in X and Y directions | --- ### Key Electronic & Structural Features #### 1. Floating Mechanism The "Floating" design is the most significant electronic-mechanical feature. It allows the connector to shift slightly (usually ±0.5 mm) to: * Absorb mating misalignments during automated assembly. * Reduce stress on solder joints caused by thermal expansion or vibration. * Ensure a stable electrical connection in harsh automotive environments. #### 2. High-Speed Signal Integrity The internal contact structure is optimized to maintain impedance control. This makes it suitable for: * LVDS (Low-Voltage Differential Signaling) * MIPI CSI-2/DSI * PCIe Gen 3 protocols #### 3. Power and Signal Handling * **Current Rating:** Typically around 0.5A per pin. * **Voltage Rating:** Usually 50V AC/DC. * **Contact Resistance:** Low milliohm (mΩ) range to minimize heat generation and signal loss. --- ### Part Number Decoder (Nomenclature) While specific to the manufacturer's internal logic, the string generally breaks down as follows: 1. **M2PH**: Series identifier (0.5mm pitch, floating type). 2. **S2H**: Socket/Header configuration and stack height indicator. 3. **A4**: Pin count (40 positions). 4. **R**: Right-angle orientation. 5. **N**: Plating or packaging variation (often denotes Nickel barrier or Tape & Reel). --- ### Typical Applications * **Automotive:** Infotainment systems, ADAS cameras, and ECU modules. * **Industrial:** Robotics, PLC controllers, and high-end imaging sensors. * **Computing:** Server blade interconnects where vibration is a factor.
