The **A-RJ45-DFR-R** is a specialized electronic component primarily categorized as a **Modular Connector (RJ45)** designed for industrial or high-reliability applications. Specifically, it is a ruggedized, panel-mount RJ45 jack. --- ### 1. General Specifications Below is a breakdown of the typical technical characteristics for this part: | Characteristic | Specification | | :--- | :--- | | **Connector Type** | RJ45 (8P8C) | | **Mounting Type** | Panel Mount / D-Flange | | **Shielding** | Shielded (Metal Housing) | | **Orientation** | Right Angle or Straight (Model dependent) | | **Ingress Protection** | Often IP65/IP67 (when mated/capped) | | **Material** | Thermoplastic / Die-cast Zinc | --- ### 2. Key Features and Design #### **D-Flange Standard** The "DF" in the part number usually refers to the **D-Series Flange**. This is a standardized mounting shape (often used in the XLR audio world) that allows it to be screwed directly into a rack panel or a wall plate with a uniform cutout. #### **Shielding & Grounding** This part is typically shielded. In electronic circuits, this is critical for: * Reducing Electromagnetic Interference (EMI). * Protecting data integrity in "noisy" industrial environments. * Ensuring a continuous ground path from the cable to the chassis. #### **Durability (Ruggedization)** Unlike standard plastic RJ45 jacks found on PC motherboards, the A-RJ45-DFR-R is built for: * **High Mating Cycles:** Designed to be plugged and unplugged thousands of times. * **Vibration Resistance:** The housing prevents the internal pins from losing contact during mechanical stress. --- ### 3. Application Use Cases This component is commonly found in the following sectors: 1. **Pro Audio/Visual:** Used in stage boxes and digital mixers for Dante or EtherCON networking. 2. **Industrial Automation:** Connecting PLCs (Programmable Logic Controllers) to factory networks. 3. **Telecommunications:** External patch panels where a robust physical interface is required. --- ### 4.
