The **M2REB-S54-R** is a specific connector component, typically part of a high-density interconnect system used in industrial and automotive electronics. It is primarily associated with **JAE (Japan Aviation Electronics)** or similar high-precision connector manufacturers. --- ### Technical Specifications The part belongs to a family of surface-mount or cable-to-board connectors designed for space-constrained environments. | Feature | Specification | | :--- | :--- | | **Part Number** | M2REB-S54-R | | **Connector Type** | Receptacle / Socket | | **Number of Positions** | 54 Pins | | **Mounting Type** | Surface Mount (SMT) or Cable-end (depending on series) | | **Pitch** | Typically 0.5mm or 0.8mm | | **Contact Material** | Copper Alloy | | **Plating** | Gold (Au) over Nickel (Ni) | | **Packaging** | Reel (-R suffix usually denotes Tape & Reel) | --- ### Key Electronic Components & Design #### 1. Housing Material The body is usually made of a **Liquid Crystal Polymer (LCP)** or high-temperature thermoplastic. This allows the part to withstand the heat of lead-free reflow soldering processes without warping. #### 2. Contact Geometry The "S54" indicates a high-density 54-pin configuration. These contacts are designed for: * **Low Insertion Force (LIF):** To prevent damage to the pins during assembly. * **Wiping Action:** The physical design ensures that any surface oxidation is scraped off during mating to maintain low contact resistance. #### 3. Signal Integrity Because of the high pin count and small pitch, these connectors are often rated for high-speed data transmission. They include: * **Shielding:** Optional metallic shells to reduce Electromagnetic Interference (EMI). * **Low Impedance:** Designed to minimize signal reflection in digital circuits. --- ### Common Applications Due to its 54-pin high-density layout, the M2REB-S54-R is commonly found in: * **Automotive Infotainment:** Connecting display panels to the main PCB. * **Industrial Automation:** Interface modules for PLCs or robotic controllers. * **Consumer Electronics:** Internal board-to-board connections in laptops or high-end cameras. --- ### Installation Notes * **Soldering:** Use a precise stencil for solder paste application to avoid bridging between the 0.5mm/0.8mm pitched leads. * **Mating:** Ensure alignment before applying downward pressure to avoid bending the 54 delicate pins.
