The part number **570-059NF05GR** refers to a high-performance electrical connector component manufactured by **Glenair**. Specifically, it belongs to the **Series 570** line, which focuses on subminiature rectangular connectors designed for rugged environmental conditions. ### 1. Part Number Breakdown To understand the electronic and mechanical properties, we can decode the nomenclature: | Segment | Code | Description | | :--- | :--- | :--- | | **Series** | 570 | Subminiature Rectangular Connector Accessory/Housing. | | **Designator** | 059 | Specific shell size or configuration code (typically a protective cover). | | **Material/Finish** | NF | Aluminum shell with Cadmium Olive Drab finish over Electroless Nickel. | | **Shell Size** | 05 | Size 05 (refers to the physical footprint/mating interface). | | **Hardware** | GR | Indicates specific attachment hardware (e.g., Gasket and Rope/Lanyard). | --- ### 2. Technical Specifications This component is primarily a **protective cover** for Series 570 connectors. Its electronic significance lies in its ability to protect sensitive signal pins and maintain EMI/RFI integrity. * **Conductivity:** The "NF" finish is highly conductive, ensuring that the cover maintains electrical continuity with the connector shell for electromagnetic shielding. * **Environmental Protection:** Designed to meet MIL-DTL-83513 standards (Micro-D style), providing a seal against dust, moisture, and debris when the connector is not in use. * **Corrosion Resistance:** The Cadmium/Nickel finish provides 500+ hours of salt spray resistance, critical for aerospace and naval electronics. * **Coupling:** Includes a secure attachment mechanism (usually a wire rope or lanyard) to prevent loss during maintenance operations. --- ### 3. Common Applications Given its "NF" (Military-grade) finish, this part is used in high-reliability environments: 1. **Avionics:** Protecting communication ports on flight control systems. 2. **Defense Systems:** Ruggedized handheld radios and tactical equipment. 3. **Space Exploration:** Used in satellite instrumentation where weight and size (subminiature) are critical. 4. **Oil & Gas:** Downhole electronics requiring robust protection from harsh surface conditions. --- ### 4.
