The part number **507T175NF3101** refers to a high-performance **Micro-D Backshell** manufactured by **Glenair**. These components are critical in aerospace, defense, and industrial applications where electromagnetic interference (EMI) protection and mechanical strain relief are required for connectors. --- ### Part Number Breakdown Glenair part numbers are descriptive. Here is the technical breakdown for **507T175NF3101**: | Segment | Code | Description | | :--- | :--- | :--- | | **Series** | 507 | Micro-D Backshell, Top Entry | | **Basic Part No.** | T175 | Standard Profile, EMI/RFI Shielding | | **Finish** | NF | Cadmium, Olive Drab over Electroless Nickel | | **Shell Size** | 31 | For 31-contact Micro-D connectors | | **Hardware** | 01 | Female Screwlock (used to secure to the mating connector) | --- ### Technical Specifications This component is designed to house the wiring exiting a Micro-D connector (MIL-DTL-83513). * **Material:** Aluminum Alloy (6061-T6). * **Plating:** **NF (Cadmium Olive Drab)**. This provides excellent corrosion resistance (500-hour salt spray rating) and high electrical conductivity for EMI shielding. * **Entry Style:** **Top Entry**. The cable exits straight out from the back of the connector. * **Shielding:** Designed to provide 360° EMI/RFI protection when used with shielded cables and conductive gaskets. * **Mechanical Protection:** Provides strain relief, preventing the delicate 24 AWG or 26 AWG wires of a Micro-D connector from breaking due to vibration or tension. --- ### Applications Due to its rugged construction and specific plating, this part is commonly found in: 1. **Avionics:** Flight control systems where EMI could disrupt signals. 2. **Military Ground Vehicles:** Systems requiring high corrosion resistance in outdoor environments. 3. **Space Systems:** High-density interconnects where space is limited but reliability is non-negotiable. --- ### Installation Note When installing the 507T175NF3101, ensure that the cable shield is properly "dressed" or folded back over the backshell's internal platform to maintain electrical continuity for the EMI shield.
