These parts are designed for aerospace, defense, and high-performance industrial applications where space is limited and environmental protection is critical. --- ### 1. Technical Specifications Breakdown The part number follows a specific nomenclature used by Glenair to define the materials, finish, and mechanical features. | Feature | Description | | :--- | :--- | | **Manufacturer** | Glenair | | **Series** | 507 (Micro-D Backshell) | | **Basic Part No.** | 059 (Standard Profile, Top Entry) | | **Finish Code (NF)** | Aluminum / Cadmium with Olive Drab Chromate | | **Shell Size (05)** | Fits 05 Shell Size (Standard Micro-D layout) | | **Hardware Code (L)** | Low Profile Jackscrews | | **Strain Relief (L)** | Latch/Clamp mechanism for cable security | --- ### 2. Key Component Features * **Material & Plating (NF):** The "NF" designation indicates an Aluminum alloy base plated with Cadmium over Electroless Nickel. This provides excellent corrosion resistance (500+ hours of salt spray) and electrical conductivity for EMI shielding. * **Top Entry Design:** The "059" series typically features a straight (top) entry for wires, allowing for streamlined cable routing in tight enclosures. * **EMI/RFI Protection:** This backshell is designed to provide 360° shielding to protect sensitive signals from electromagnetic interference. * **Low Profile:** The "L" hardware ensures that the connector assembly remains as compact as possible, which is essential for "box-to-box" wiring in avionics. --- ### 3. Applications Due to its rugged construction and shielding capabilities, this part is commonly found in: 1. **Avionics:** Flight control systems and cockpit instrumentation. 2. **Military Hardware:** Handheld tactical radios and ruggedized computers. 3. **Space Systems:** Satellites where weight and size constraints are extreme. 4. **Medical Imaging:** High-density signal processing equipment. --- ### 4. Installation & Compatibility This backshell is designed to be used with **MIL-DTL-83513** type Micro-D connectors. When assembling, it is critical to ensure the wire bundle does not exceed the internal diameter of the entry port to maintain the integrity of the strain relief clamp.
