The **27DRDK-R** is a specific part number typically associated with **D-Subminiature connectors**. Based on industry standard nomenclature (often used by manufacturers like Adam Tech or NorComp), this part is a high-density, right-angle, D-Sub connector designed for PCB mounting. --- ### 1. Technical Specifications The following table breaks down the core technical characteristics of the 27DRDK-R: | Feature | Specification | | :--- | :--- | | **Connector Type** | High-Density D-Sub | | **Gender** | Female (Receptacle/Socket) | | **Number of Positions** | 15 Pins (usually 3 rows in a Size 9 shell) | | **Orientation** | Right-Angle (90°) | | **Mounting Type** | Through-Hole (PCB Mount) | | **Contact Plating** | Gold Flash or Selective Gold | | **Current Rating** | 1A to 3A per contact | | **Housing Material** | PBT Thermoplastic (UL 94V-0 rated) | --- ### 2. Physical Design Elements * **Right-Angle Configuration:** The "R" in the suffix usually denotes "Right-Angle." This allows the connector to be mounted on the edge of a circuit board so that the interface sits perpendicular to the PCB surface. * **Board Locks / Rivets:** The "DK" in the part string often refers to specific mounting hardware, such as integrated board locks or threaded inserts (like 4-40 UNC threads) that secure the connector to the board and provide a point for the mating cable to screw into. * **High Density:** Unlike standard D-subs, high-density versions use smaller pins packed more closely together. A 15-pin high-density connector fits within the physical shell size of a standard 9-pin connector. --- ### 3. Common Applications These connectors are robust and widely used in legacy and industrial electronics: 1. **VGA Video Interfaces:** The 15-pin version of this connector is the standard interface for VGA video output on older PCs and industrial monitors. 2. **Industrial Automation:** Used for serial data communication and sensor arrays where space is limited but multiple signal lines are required. 3. **Telecommunications:** Employed in networking hardware for diagnostic ports. --- ### 4. Comparison: Standard vs. High Density | Feature | Standard D-Sub | High Density (27DRDK-R type) | | :--- | :--- | :--- | | **Pin Rows** | 2 Rows | 3 Rows | | **Pin Spacing** | 2.77mm | 2.29mm | | **Example Pins** | 9 Pin | 15 Pin (Size E) |
