The part number **48AV-2YH3-R** refers to a specific type of **Low Profile D-Sub Connector**, commonly used in computing, telecommunications, and industrial equipment where space is limited. Below is a detailed breakdown of its specifications and electronic characteristics. --- ### 1. General Specifications This component is a high-density, right-angle connector designed for PCB (Printed Circuit Board) mounting. | Feature | Specification | | :--- | :--- | | **Connector Type** | D-Subminiature (D-Sub) | | **Gender** | Female (Socket/Receptacle) | | **Mounting Type** | Right Angle (Through-Hole) | | **Number of Positions** | Typically 15 or 9 (Standard density varies by series) | | **Profile** | Low Profile (Space-saving height) | | **Compliance** | RoHS Compliant | --- ### 2. Key Electronic Characteristics These connectors are engineered to maintain signal integrity while handling standard logic-level currents. * **Contact Resistance:** Generally less than **15mΩ to 30mΩ**. This ensures minimal voltage drop across the connection. * **Current Rating:** Typically rated for **1A to 3A** per contact, depending on the specific gauge of the mating wire. * **Dielectric Withstanding Voltage:** Usually rated for **500V AC to 1000V AC** for one minute, preventing arcing between pins. * **Insulation Resistance:** Minimum of **1000MΩ** at 500V DC, ensuring high isolation between adjacent signals. --- ### 3. Physical & Material Composition The "R" in the suffix often denotes compliance with environmental standards or a specific packaging style (like Reel or RoHS). * **Housing:** High-temperature thermoplastic (UL94V-0 rated), allowing it to withstand wave soldering processes. * **Contacts:** Copper alloy with selective **Gold Plating** on the contact area for superior conductivity and corrosion resistance. * **Shell:** Steel with Nickel or Tin plating for EMI/RFI shielding. * **Hardware:** Usually includes "Boardlocks" or "Harpoons" to provide mechanical stability on the PCB during and after soldering. --- ### 4. Common Applications * **VGA Interfaces:** Often used in video output for compact devices. * **Serial Ports:** RS-232 communication in industrial controllers. * **Networking:** Data transmission in routers and switches. * **Embedded Systems:** Connecting peripheral modules to a mainboard in tight enclosures.
