The part number **570-059M05GL** identifies a specific high-performance connector from the **Glenair 570 series**. These are typically ultra-miniature, high-density connectors used in aerospace, defense, and specialized industrial applications. --- ### 1. Component Overview The 570 series is part of Glenair’s **High-Density (HD) Stacker** or **Mezzanine** connector family. These are designed for board-to-board applications where space is at a premium and high signal integrity is required. ### 2. Technical Specifications Based on the standard nomenclature for this series, here are the key electronic and physical characteristics: | Feature | Specification Details | | :--- | :--- | | **Manufacturer** | Glenair | | **Series** | 570 (High Density / Ultra-Miniature) | | **Number of Contacts** | 59 Contacts | | **Mounting Type** | Surface Mount (SMT) or Vertical Stacker | | **Contact Pitch** | Typically 0.025 inch (0.635 mm) | | **Plating** | Gold (indicated by 'GL') for superior conductivity and oxidation resistance | | **Material** | High-temperature thermoplastic insulators; Copper alloy contacts | --- ### 3. Key Electronic Characteristics * **High Pin Density:** Designed to fit 59 signal paths into a very small footprint, allowing for complex circuit routing in compact devices. * **Signal Integrity:** Engineered to minimize crosstalk and impedance mismatches, making it suitable for high-speed data transmission. * **Durability:** Features ruggedized construction capable of withstanding significant vibration and shock, typical of MIL-SPEC (Military Specification) style hardware. * **Low Profile:** The "M05" designation usually refers to a specific height (mating height), allowing for very tight stacking of Printed Circuit Boards (PCBs). ### 4. Typical Applications * **Aerospace Avionics:** Cockpit displays and flight control computers. * **Military Electronics:** Man-portable radios and ruggedized tablets. * **Space Systems:** Satellite instrumentation where weight and size are critical. * **Medical Imaging:** High-resolution sensors requiring high-density interconnects. --- ### 5. Identification Breakdown While specific internal Glenair codes can vary, the part number generally breaks down as follows: * **570:** Series identifier (High-density board-to-board). * **059:** Pin count (59 positions). * **M05:** Height/Type code (Specific stack height between boards). * **GL:** Finish/Plating (Gold plating over nickel).
