The part number **507-059M04GR** refers to a high-reliability **Micro-D connector** manufactured by **Glenair**. This specific part belongs to the 507 series, which typically features "Backshells" or "Connector Accessories" designed for D-Subminiature connectors. --- ### Technical Specifications Breakdowns | Specification | Details | | :--- | :--- | | **Manufacturer** | Glenair | | **Series** | 507 (Micro-D Backshells) | | **Connector Body Material** | Aluminum Alloy | | **Plating** | Electroless Nickel (M) | | **Entry Type** | Round, Top Entry | | **Shell Size** | 04 (Corresponds to specific pin count/shell dimensions) | | **Hardware Options** | G (Gold Plated) / R (Rear Mount or specialized hardware code) | --- ### Component Breakdown The part number follows a modular logic typical of Glenair’s coding system: 1. **507**: The base series for Micro-D EMI/RFI Backshells. These are used to provide mechanical protection and electromagnetic interference shielding to the wire-to-connector interface. 2. **-059**: The specific design configuration (often a "top entry" style for cable management). 3. **M**: Indicates the **Finish**. "M" stands for **Electroless Nickel**, which offers excellent conductivity for shielding and good corrosion resistance. 4. **04**: Indicates the **Shell Size**. In the Micro-D world, shell sizes correlate to the number of contacts (e.g., 9, 15, 21, 25, 31, 37, 51, or 100 pins). 5. **G**: Refers to the **Hardware/Attachment type**, typically indicating a specific screw-lock or jackpost configuration. 6. **R**: Usually denotes **Rear-mount** capability or a specific strain relief option. --- ### Key Applications These parts are designed for mission-critical environments where space is limited but high performance is required: * **Aerospace & Defense:** Used in avionics and satellite systems. * **High-Speed Data:** Providing EMI protection for sensitive signals. * **Medical Electronics:** Where compact, shielded connections are necessary. ### Mechanical Features * **EMI/RFI Shielding:** The metal housing ensures that the signal is protected from external interference. * **Strain Relief:** Prevents the wires from being pulled out of the connector pins during vibration or handling. * **Compact Profile:** Designed specifically for the Micro-D (MIL-DTL-83513) footprint, which is significantly smaller than standard D-Subs.
