The part number **507-059NF05LR** refers to a high-performance backshell manufactured by **Glenair**. This component belongs to the interconnect accessory family, specifically designed for use with Micro-D (MIL-DTL-83513) connectors. --- ### ## Technical Specifications Below is a breakdown of the technical characteristics associated with this specific part number: | Feature | Specification | Description | | :--- | :--- | :--- | | **Manufacturer** | Glenair | Industry leader in interconnect solutions. | | **Series** | 507-059 | EMI/RFI Micro-D Backshell, Eliptical Entry. | | **Shell Size** | 05 | Corresponds to the layout of the Micro-D connector. | | **Material/Finish** | NF | Aluminum Alloy with Olive Drab Cadmium plating. | | **Hardware Type** | LR | Latching/Locking post for secure attachment. | | **Entry Type** | Elliptical | Allows for a wider cable bundle entry. | --- ### ## Component Breakdown #### 1. Material & Finish (NF) The "NF" code signifies **Aluminum with Cadmium plating over Electroless Nickel**. * **Durability:** Provides excellent corrosion resistance (500-hour salt spray rating). * **Conductivity:** Highly conductive for EMI/RFI shielding applications. * **Color:** Typically an Olive Drab (dark green) hue. #### 2. EMI/RFI Protection This backshell is engineered to provide a 360-degree shield termination. It prevents electromagnetic interference (EMI) from leaking in or out of the connection point, which is critical in aerospace and defense electronics. #### 3. Hardware (LR) The "LR" suffix indicates the type of mounting hardware. These are typically **locking/latching posts** or extended jackscrews that ensure the backshell remains vibration-proof when mated to the bulkhead or another connector. --- ### ## Applications Because of its rugged construction and shielding capabilities, the 507-059 series is commonly found in: * **Aerospace Avionics:** High-density wiring in cockpit instruments. * **Military Communications:** Ruggedized handheld and vehicle radios. * **Satellite Systems:** Where weight and space (Micro-D form factor) are at a premium. ---
