The **EB412R15** is a specialized electronic component, typically categorized as a **Terminal Block Connector** or an **Edge Card Connector**, often used in industrial power supplies, telecommunications, and high-reliability instrumentation. Below is a detailed breakdown of its specifications, electronic characteristics, and materials. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Component Type** | Edge Card / Terminal Connector | | **Number of Positions** | 12 Positions (Dual row often implied by series) | | **Pitch (Spacing)** | 0.156" (3.96mm) or 0.100" depending on sub-series | | **Current Rating** | 3A to 5A (Standard for this series) | | **Voltage Rating** | 600V AC (RMS) | | **Mounting Type** | Through-hole / Right Angle / PC Mount | --- ### 2. Physical and Material Composition The reliability of the EB412R15 comes from its construction materials, designed to withstand thermal stress and oxidation. * **Contacts:** Usually made of **Phosphor Bronze** or **Beryllium Copper**. These alloys provide excellent spring properties to maintain a tight electrical connection over thousands of cycles. * **Plating:** Most variants feature **Gold plating** over Nickel on the contact area to prevent corrosion and ensure low contact resistance. The "tails" are typically Tin-plated for easier soldering. * **Insulator:** High-grade **Diallyl Phthalate (DAP)** or **Polyphenylene Sulfide (PPS)**. These materials are chosen for their high dielectric strength and resistance to high soldering temperatures. --- ### 3. Electronic Performance Features 1. **Low Contact Resistance:** Typically measured under **10 milliohms**, ensuring minimal voltage drop across the connector. 2. **High Insulation Resistance:** Usually rated at **5000 Megohms** minimum, preventing leakage current between adjacent pins. 3. **Durability:** Rated for high "mating cycles," meaning the physical spring tension of the pins does not degrade quickly after repeated insertions. --- ### 4. Common Applications * **Power Supplies:** Used as an interface between a backplane and a modular power unit. * **Industrial Controls:** Connecting PLC (Programmable Logic Controller) modules to field wiring. * **Legacy Computing:** Often found in older rack-mount systems for signal routing between daughterboards. ---
