The part number **570-059M06LR** typically refers to a high-performance **Micro-D Connector** backshell, often manufactured by companies like **Glenair**. These components are critical in aerospace, defense, and high-reliability industrial electronics. --- ### 1. Component Overview This specific part is an **EMI/RFI Protective Backshell**. Its primary function is to provide strain relief for cables and shield the signals inside from electromagnetic interference. ### 2. Technical Specifications Below is a breakdown of the typical characteristics for this series: | Feature | Specification | | :--- | :--- | | **Connector Series** | Micro-D (MIL-DTL-83513 type) | | **Material** | Aluminum Alloy (usually 6061-T6) | | **Plating/Finish** | Electroless Nickel (denoted by "M") | | **Entry Style** | Low Profile / Round Entry | | **Configuration** | Straight or 90-degree (depending on sub-code) | | **Hardware** | Hex Head Jackscrews | --- ### 3. Key Components & Features #### A. Material and Finish (The "M" Code) * The **"M"** in the part number signifies **Electroless Nickel**. * **Purpose:** This provides excellent conductivity for EMI shielding and high resistance to corrosion. It is the standard finish for space-grade and military applications. #### B. Shell Size (The "059" Code) * This refers to the specific dimensions and layout required to fit a Micro-D connector with a specific contact count (often 9, 15, 21, 25, 31, 37, 51, or 100 pins). #### C. EMI/RFI Shielding * The backshell acts as a Faraday cage. By grounding the cable braid to the backshell, it prevents external electrical noise from corrupting data signals and prevents the cable from emitting its own interference. #### D. Strain Relief * The **"LR"** (Long Relief) or similar suffix indicates the physical housing style. It ensures that mechanical tension on the cable does not pull the fragile pins out of the connector housing. --- ### 4. Common Applications Due to its ruggedized nature, this part is used in: 1. **Avionics:** Cockpit instrumentation and flight control systems. 2. **Satellites:** Data handling systems where weight and EMI are concerns. 3. **Medical Equipment:** High-resolution imaging sensors. 4. **Downhole Drilling:** Rugged sensors used in oil and gas exploration. ---
