The **M2REB-RB4-R** is a specific electronic component within the category of **Board-to-Board Connectors** or **High-Density Interface Connectors**, typically manufactured by companies like **I-PEX** or similar specialty connector firms. It is designed for high-speed signal transmission in compact electronic devices. --- ### 1. General Specifications Below is a breakdown of the typical technical attributes for this series: | Attribute | Specification | | :--- | :--- | | **Connector Type** | Receptacle (Socket) | | **Mounting Type** | Surface Mount (SMT) | | **Pitch** | 0.4mm or 0.5mm (depending on specific sub-series) | | **Orientation** | Right Angle or Vertical (Standard is Vertical) | | **Shielding** | Full Metal Shielding (EMI protection) | | **Pin Count** | Variable (RB4 series often denotes specific configuration) | --- ### 2. Key Electronic Features #### A. High-Speed Data Transmission These connectors are engineered to handle high-frequency signals. They are commonly used for: * **eDP (embedded DisplayPort)**: For 4K/8K laptop screens. * **USB 3.1 / 3.2**: High-speed peripheral data. * **PCIe Gen 3 / 4**: Internal component communication. #### B. EMI/EMC Performance The "R" suffix often denotes **Robust** or **Reinforced** shielding. The metal shell provides a 360-degree ground contact, which: 1. Reduces electromagnetic interference (EMI). 2. Ensures signal integrity in noisy environments (like mobile phones or tablets). #### C. Mechanical Reliability * **Wiping Effect**: The contact design ensures that dust or oxides are wiped away during insertion. * **Locking Mechanism**: These often feature a friction lock or a mechanical "click" to ensure they do not vibrate loose. --- ### 3. Common Applications Due to its low profile and high performance, the M2REB-RB4-R is found in: * **Laptops/Tablets**: Connecting the motherboard to the LCD panel. * **Smartphones**: Internal camera module or battery management board connections. * **Drones/IoT**: High-density sensors where space is at a premium. --- ### 4. Technical Pinout Representation While specific pinouts depend on the PCB design, the electrical characteristics usually follow this pattern: ```yaml Electrical_Properties: Voltage_Rating: 50V AC/DC Current_Rating: 0.3A to 0.5A per pin Contact_Resistance: < 40 mOhms Dielectric_Withstanding: 250V AC for 1 minute ```
