The model number **EB412R15SGX15** corresponds to a specific configuration of a **Card Edge Connector**, typically manufactured by brands like Sullins Connector Solutions. These components are used to connect printed circuit boards (PCBs) to a motherboard or backplane. --- ## Technical Specifications Breakdown The alphanumeric code provides specific details regarding the physical and electrical characteristics of the part: | Feature | Specification | Description | | :--- | :--- | :--- | | **Series** | EB | Standard Edgeboard Series | | **Pitch** | 0.100" (2.54mm) | The distance between the center of one pin and the next | | **Contact Positions** | 15/30 | 15 positions per side (30 total contacts) | | **Contact Type** | R | Right Angle / Side Entry orientation | | **Mounting Style** | 1 | Through-hole (typically with mounting ears/holes) | | **Plating** | SG | Selective Gold plating (Gold on contact area, Tin on leads) | | **Mod Code** | X15 | Special configuration (often relates to tail length or specific insulator material) | --- ## Key Electronic Characteristics ### 1. Contact Material and Plating * **Selective Gold (SG):** This is a cost-effective high-performance plating. Gold is used on the mating surface to ensure low contact resistance and prevent oxidation, while Tin is used on the solder tails to improve solderability. * **Base Material:** Usually Phosphor Bronze or Beryllium Copper, providing high spring tension and durability. ### 2. Geometry and Mounting * **Right Angle (R):** The pins are bent at a 90-degree angle. This allows the daughter card to be inserted parallel to the main motherboard, saving vertical space in rack-mounted systems. * **Dual Readout:** The connector has contacts on both the top and bottom rows, allowing for independent signals on both sides of the inserted PCB. ### 3. Electrical Ratings * **Current Rating:** Typically 3 Amps per contact. * **Voltage Rating:** Usually rated for 600 VDC or VAC (RMS) at sea level. * **Insulation Resistance:** 5000 Megaohms minimum. --- ## Typical Applications These connectors are widely used in legacy industrial equipment and specific communication hardware: * **Test and Measurement:** Connecting modular sensor boards to a data logger. * **Industrial Controls:** Interfacing PLC modules. * **Legacy Computing:** Connecting expansion cards to a backplane. * **Telecommunications:** Signal routing in rack-mounted switching equipment.
