The part number **570-059NF02GL** refers to a high-performance electrical connector backshell manufactured by **Glenair**. These components are critical in aerospace, defense, and industrial applications for protecting electrical connections. --- ### 1. Component Identification This specific part belongs to the **Series 570** product line, which focuses on protective covers and environmental backshells for circular connectors. | Specification | Detail | | :--- | :--- | | **Manufacturer** | Glenair | | **Component Type** | Connector Backshell / Protective Cover | | **Material** | Aluminum Alloy (Standard) | | **Application** | Cable Strain Relief & Environmental Sealing | ### 2. Part Number Breakdown Understanding the nomenclature helps identify the exact features of the component: * **570**: The Series number (Glenair standard series). * **059**: The specific design configuration (often denotes a specific angle or profile). * **NF**: The Finish code. **NF** stands for **Olive Drab Cadmium over Electroless Nickel**. This provides excellent corrosion resistance (500-hour salt spray) and is conductive for EMI shielding. * **02**: The Shell Size identifier. This indicates which connector size (e.g., Size 10 or 12 depending on the series) the backshell is designed to fit. * **GL**: Specific hardware or gasket options (often denotes a "Gland" nut or specific internal lining). ### 3. Technical Features The **570-059NF02GL** is designed with the following technical attributes: * **Environmental Protection:** It acts as a barrier against moisture, dust, and chemicals from entering the rear of the connector. * **Strain Relief:** Prevents the wires from being pulled out of the connector pins during vibration or mechanical stress. * **EMI/RFI Shielding:** Due to the conductive **NF** plating, it helps maintain electrical continuity and protects the signal from electromagnetic interference when paired with shielded cables. * **Durability:** The aluminum construction ensures it can withstand high-impact environments common in military avionics. ### 4. Typical Applications * **Avionics:** External sensors and communication arrays. * **Military Vehicles:** Ground-based tactical equipment. * **Marine:** Sub-surface or deck-side electrical systems (due to the high corrosion resistance of the Cadmium finish). ---
