The **M2REB-S31-R2** is a specific electronic component belonging to the category of high-speed, high-density connectors, typically used in automotive, industrial, or telecommunications hardware. It is manufactured by **JAE (Japan Aviation Electronics Industry)**. Below is a breakdown of its technical specifications and electronic properties. --- ### 1. Technical Specifications | Parameter | Specification | | :--- | :--- | | **Connector Type** | Receptacle (Socket) | | **Series** | M2 Series (Automotive grade) | | **Number of Positions** | 31 Pins | | **Mounting Type** | Surface Mount (SMT) / Right Angle | | **Contact Material** | Copper Alloy | | **Plating** | Tin or Gold (depending on specific sub-version) | | **Voltage Rating** | 50V AC/DC | | **Current Rating** | 0.5A per pin | --- ### 2. Key Electronic Features #### A. High-Density Signal Integrity The "S31" indicates a 31-position interface. Despite the high pin count, the connector is designed to maintain signal integrity across high-speed data lines, often used for infotainment or display signals in vehicles. #### B. Surface Mount Technology (SMT) The "R2" suffix usually refers to the packaging or a specific revision of the right-angle SMT design. This allows for automated pick-and-place assembly on PCBs, reducing manufacturing costs and increasing precision. #### C. Environmental Robustness As an automotive-grade component, it is built to withstand: * **Vibration:** High resistance to mechanical shocks typical in moving vehicles. * **Temperature:** Usually rated for wide temperature ranges (e.g., -40°C to +85°C). --- ### 3. Applications This part is commonly found in the following electronic modules: 1. **Automotive Infotainment:** Connecting LCD displays to the main processing board. 2. **ADAS Systems:** Linking camera modules or sensors to the Electronic Control Unit (ECU). 3. **Industrial Controls:** Used in compact PLC units where space is limited but high pin density is required. --- ### 4. Part Number Breakdown * **M2**: Series designation (Low profile, high-density). * **REB**: Receptacle style (Board side). * **S31**: Number of contacts (31). * **R2**: Packaging/Revision code (typically Tape and Reel for SMT).
