The part number **507T175E0901H** corresponds to a high-performance **Micro-D Connector** manufactured by **Glenair**. These connectors are engineered for applications requiring extreme reliability, space savings, and high-density interconnects. --- ## 1. Technical Specifications The part number follows a specific nomenclature used by Glenair for their 507 series (Micro-D Backshells and Connectors). | Parameter | Specification | | :--- | :--- | | **Series** | 507 (Micro-D Backshell / Connector System) | | **Shell Material** | Aluminum Alloy | | **Plating** | Electroless Nickel (Code 'E') | | **Contact Density** | High Density (Micro-D standard) | | **Configuration** | Specialized EMI/RFI Protected Backshell | | **Operating Temp** | -55°C to +150°C | --- ## 2. Key Features and Design ### A. Material & Finish The **"E"** in the part number signifies **Electroless Nickel** plating. This is preferred in electronic systems for: * Excellent corrosion resistance. * Superior electrical conductivity for EMI shielding. * A sleek, professional aesthetic. ### B. EMI/RFI Protection This specific assembly is designed as an **EMI/RFI Shield Termination** backshell. It prevents electromagnetic interference from leaking into or out of the cable assembly, which is critical for sensitive electronics like avionics or medical imaging. ### C. Mechanical Durability * **Strain Relief:** Provides mechanical support to the wires, preventing solder joints or crimps from breaking under vibration. * **Low Profile:** The "T" designator often refers to a specific entry profile (Top or Side entry), allowing the connector to fit in tight electronic enclosures. --- ## 3. Common Applications Due to its ruggedized nature and high-density pin count, this part is typically found in: 1. **Aerospace & Defense:** Satellite wiring harnesses, UAV flight controllers, and cockpit instrumentation. 2. **Medical Electronics:** Portable diagnostic equipment and high-resolution imaging systems. 3. **Industrial Robotics:** Control systems where space is limited but high signal integrity is required. 4. **Downhole Drilling:** Electronic sensors used in oil and gas exploration. --- ## 4. Part Number Breakdown (Generalized) * **507:** Basic Series (Micro-D Backshell). * **T:** Entry Type (Typically Top entry). * **175:** Specific design or size code. * **E:** Finish (Electroless Nickel). * **09:** Size or number of contacts (often refers to a 9-pin shell size). * **01H:** Hardware or specific cable entry modifications. ---
