The part number **507T175E0901E** corresponds to a specific high-performance **Micro-D connector** manufactured by **Glenair**. These connectors are widely used in aerospace, defense, and industrial applications where space is limited and reliability is critical. --- ## Technical Specifications Overview | Parameter | Specification Details | | :--- | :--- | | **Manufacturer** | Glenair | | **Series** | 507 (Micro-D Backshell/Connector Accessory) | | **Connector Type** | Micro-D (MIL-DTL-83513 type) | | **Shell Material** | Aluminum Alloy | | **Plating** | Electroless Nickel (Code E) | | **Hardware Type** | Extended Jackscrew | --- ## Part Number Breakdown To understand the electronic and mechanical properties, we can decode the part number string: ### 1. Series (507) Refers to the **Glenair 507 Series**, which typically identifies specialized backshells and accessories for Micro-D connectors. These are designed to provide EMI/RFI protection and strain relief for wire harnesses. ### 2. Designator (T) Indicates the specific entry style or configuration. "T" usually refers to a **Top Entry** configuration, meaning the wires exit the backshell straight out from the mating face. ### 3. Size/Layout (175) This indicates the shell size and contact arrangement. In the Micro-D ecosystem, this determines the physical dimensions and the number of pins/sockets the backshell is designed to accommodate. ### 4. Finish/Plating (E) The letter **E** stands for **Electroless Nickel**. * **Benefits:** Excellent conductivity for EMI shielding, high corrosion resistance, and a professional aesthetic. * **Conductivity:** Highly conductive, making it ideal for grounding shells. ### 5. Exit/Entry Size (09) Refers to the cable entry diameter or specific slot width (0.90 inches or a specific scaled code depending on the exact drawing). ### 6. Hardware (01E) Indicates the mounting hardware included. The **E** suffix here usually denotes **Extended Jackscrews**, which allow for manual tightening without tools, common in environments where frequent mating/unmating occurs. --- ## Key Applications * **Aerospace:** Used in satellites and avionics where weight and space are at a premium. * **Military:** Ruggedized for high-vibration environments (tanks, handheld radios). * **Medical:** High-density signal transmission for diagnostic imaging equipment. * **Subsea:** Used in pressure-balanced oil-filled (PBOF) assemblies when paired with appropriate seals. --- ## Electrical & Mechanical Benefits 1. **EMI Shielding:** The aluminum shell with electroless nickel plating provides a "Faraday Cage" effect, protecting sensitive signals from electromagnetic interference. 2. **Strain Relief:** Prevents the individual solder or crimp joints inside the connector from breaking under mechanical stress or vibration. 3. **Space Efficiency:** Micro-D connectors have a contact pitch of **.050 inch (1.27 mm)**, making them significantly smaller than standard D-Sub connectors.
