The part number **507-059NF02LR** refers to a high-performance **Micro-D Backshell** manufactured by **Glenair**. These components are critical in aerospace, defense, and high-reliability industrial electronics for protecting connector terminations. --- ### 1. Technical Specifications Breakdown The part number follows a specific nomenclature used by Glenair to define its physical and material properties: | Feature | Specification | Description | | :--- | :--- | :--- | | **Series** | 507 | Micro-D Backshell (Rectangular) | | **Basic Part No.** | 059 | Qwik-Ty® Strain Relief Style | | **Finish Code** | NF | Cadmium, Olive Drab over Electroless Nickel | | **Shell Size** | 02 | Fits 15-Contact Micro-D Connectors | | **Hardware** | LR | Latching/Recessed Screw option | --- ### 2. Key Component Features #### A. Material and Finish (NF) * **Cadmium/Olive Drab:** This finish provides excellent corrosion resistance (up to 500 hours of salt spray) and is electrically conductive, which is vital for EMI/RFI grounding. #### B. Qwik-Ty® Design * Unlike traditional circular clamps, the **Qwik-Ty** feature provides a low-profile alternative for strain relief. * It uses a simple tie-wrap or lacing tape to secure the wire bundle, reducing weight and assembly time. #### C. Compatibility * This backshell is designed specifically for **MIL-DTL-83513** type Micro-D connectors. * The "02" size indicates it is sized for a **15-pin** connector layout. --- ### 3. Application Use Cases Due to its rugged construction, this part is typically found in: * **Avionics:** Managing wire harnesses in cramped cockpit environments. * **Satellites:** Where weight reduction (using Qwik-Ty instead of heavy clamps) is essential. * **Military Ground Vehicles:** Where vibration resistance and corrosion protection are mandatory. --- ### 4.
