The part number **507-059NF06GR** refers to a high-reliability **Micro-D Backshell** manufactured by **Glenair**. These components are critical in aerospace, defense, and industrial applications where Micro-D (MIL-DTL-83513) connectors require physical protection and EMI/RFI shielding. --- ### ## Technical Specifications Breakdown The part number is alphanumeric, where each segment represents a specific feature of the backshell: | Segment | Feature | Description | | :--- | :--- | :--- | | **507** | Series | Glenair Series for Micro-D Backshells. | | **059** | Style | Indicates a **Top / Straight Entry** profile. | | **NF** | Material/Finish | Aluminum Alloy with **Cadmium/Olive Drab** plating (Conductive, provides high corrosion resistance). | | **06** | Connector Size | Fits a **9-Pin/Socket** Micro-D connector. | | **G** | Hardware | Includes **Male Jackscrews** (standard). | | **R** | Slot/Entry | Indicates a specific **Round** entry or wire bundle size configuration. | --- ### ## Key Electronic & Mechanical Functions 1. **EMI/RFI Shielding:** The "NF" finish is conductive. When paired with a shielded cable, the backshell acts as a Faraday cage, preventing electromagnetic interference from leaking in or out of the connection point. 2. **Strain Relief:** It protects the delicate solder or crimp joints inside the Micro-D connector by securing the cable bundle, preventing wire breakage caused by vibration or pulling. 3. **Environmental Protection:** While not hermetically sealed, the aluminum construction provides rugged physical protection against impact and debris in harsh environments. 4. **Grounding Path:** The conductive plating ensures a low-resistance path to ground through the connector shell, which is vital for signal integrity in sensitive electronics. --- ### ## Common Applications * **Aerospace:** Avionics suites and flight control systems. * **Military:** Handheld communication devices and radar systems. * **Space:** Satellite internal wiring (though usually requires "M" or "Z1" finish for outgassing). * **Medical:** High-density diagnostic equipment.
