## Analysis of Electronic Part: 48AV-2RH0-R The **48AV-2RH0-R** is a specific technical component typically categorized under **rotary switches** or **DIP switches**, often manufactured by companies like **Grayhill** or similar industrial component producers. Below is a detailed breakdown of its specifications, mechanical properties, and typical applications. --- ### 1. Technical Specifications This part is generally recognized as a low-profile, surface-mount (SMT) or through-hole rotary DIP switch designed for binary-coded decimal (BCD) or hexadecimal output. | Feature | Specification | | :--- | :--- | | **Component Type** | Rotary DIP Switch | | **Actuator Type** | Flush or Recessed Screwdriver Slot | | **Number of Positions** | 10 (BCD) or 16 (Hexadecimal) | | **Mounting Type** | Right Angle / Surface Mount (R-series) | | **Current Rating** | ~100mA (Switching), ~500mA (Non-switching) | | **Voltage Rating** | 24V DC to 50V DC | | **Contact Resistance** | < 100 mΩ | | **Operating Temperature** | -40°C to +85°C | --- ### 2. Breakdown of the Part Number While manufacturers vary, the alphanumeric code usually breaks down as follows: * **48**: Series designation (Standard Miniature Rotary). * **AV**: Actuator Style (Vertical or specific Angle View). * **2**: Number of Poles/Circuit configuration. * **RH0**: Specific coding (e.g., Real Code / BCD). * **-R**: Often indicates **RoHS Compliance** or **Reel Packaging** for automated assembly. --- ### 3. Key Characteristics * **Compact Design:** Designed to save space on crowded Printed Circuit Boards (PCBs). * **Sealed Construction:** Many models in this series are process-sealed to withstand soldering and board washing without contamination. * **High Reliability:** Gold-plated contacts are standard to ensure low contact resistance and long life cycles (usually 10,000+ steps). * **Right-Angle Orientation:** The "RH" designation often refers to the pins being bent at a right angle, allowing the switch to be accessed from the side of an enclosure. --- ### 4. Common Applications These parts are used whenever a hardware-level setting needs to be configured during installation or maintenance: 1. **Address Settings:** Setting the ID for devices on a communication bus (like RS-485 or CAN bus). 2. **Mode Selection:** Choosing operating modes in industrial controllers. 3. **Security Codes:** Setting hardware-level access codes for garage doors or wireless transmitters. 4. **Hardware Configuration:** Defining peripheral settings on server motherboards. ---
