The **RG1-602S-R15** is a high-performance **PCI Express (PCIe) Card Edge Connector** typically used in computing, server, and networking hardware. It is manufactured by companies such as **Lotes** and is designed to provide a physical and electrical interface between a motherboard and an expansion card (like a GPU or NIC). --- ### Technical Specifications The following table outlines the primary electronic and physical characteristics of this component: | Parameter | Specification | | :--- | :--- | | **Connector Type** | PCI Express (Card Edge) | | **Number of Pins** | 164 Pins (standard for x16 slots) | | **Pitch** | 1.00 mm | | **Mounting Type** | Through-Hole (Vertical) | | **Orientation** | Straight / Vertical | | **Data Rate Compatibility** | PCIe 3.0 / 4.0 / 5.0 (depending on material) | | **Contact Plating** | Gold over Nickel | | **Housing Material** | High-Temperature Thermoplastic (LCP) | --- ### Key Electronic Components & Features #### 1. Contact Material and Plating The pins are usually made of a copper alloy. The "R15" in the part number often denotes the thickness of the **Gold Plating** (e.g., 15 micro-inches). Gold is critical because: * It prevents oxidation. * It ensures low contact resistance for high-speed signal integrity. #### 2. Signal Integrity The connector is designed to handle high-frequency differential pairs. The spacing and internal geometry are engineered to minimize: * **Crosstalk:** Interference between adjacent signal lines. * **Insertion Loss:** Loss of signal strength as it passes through the connector. #### 3. Mechanical Stability The "S" in the suffix often indicates a specific **Solder Tail** length or a "Straddle" mount variation, though in the RG1 series, it usually refers to a standard straight solder type. The plastic housing includes "Pegs" or "Bosses" to ensure the connector is aligned perfectly on the PCB before soldering. --- ### Typical Applications * **Motherboards:** Primary slots for Graphics Processing Units (GPUs). * **Server Backplanes:** For high-speed storage or networking riser cards. * **Industrial PCs:** Modular expansion slots for I/O cards. ---
