The **DF11-28DP-2DSA** is a specific connector model within the widely used **DF11 Series** manufactured by **Hirose Electric (HRS)**. It is a dual-row, high-density pin header designed for wire-to-board and board-to-board connections. --- ### ## Technical Specifications Below are the primary electrical and physical parameters for this component: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Hirose Electric (HRS) | | **Series** | DF11 | | **Total Number of Positions** | 28 Pins (2 Rows x 14) | | **Pitch (Spacing)** | 2.00 mm (0.079") | | **Connector Type** | Header, Male Pin | | **Mounting Type** | Through Hole (Right Angle) | | **Current Rating** | 2A per contact | | **Voltage Rating** | 250V AC/DC | | **Contact Finish** | Gold or Tin (Depending on suffix) | | **Insulation Resistance** | 1000 MΩ Minimum | | **Withstanding Voltage** | 650V AC for 1 minute | --- ### ## Component Breakdown The part number itself provides a roadmap of the connector's features: 1. **DF11**: The series name (2mm pitch, double row). 2. **28**: The total number of circuits/contacts (14 pins per row). 3. **DP**: Double Row Pin Header. 4. **2**: The pitch measurement (2.0 mm). 5. **DSA**: Refers to the terminal type—**Straight Dip** (Though the 'A' can sometimes signify specific material or plating variations depending on the revision). --- ### ## Key Features & Applications #### ### 1. Space-Saving Design The 2mm pitch allows for a 40% reduction in board space compared to standard 2.54mm (0.1") headers. Despite the small footprint, it maintains a robust current capacity of 2A. #### ### 2. Polarization & Locking The housing features a "polarizing boss" or guide key. This ensures that the mating socket cannot be inserted upside down, protecting the circuit from reverse polarity damage. #### ### 3. Durability These connectors are designed for internal wiring in industrial and consumer electronics where vibration resistance and secure signal integrity are required. #### ### 4. Common Use Cases * **Industrial Automation:** Control boards and PLC modules. * **Consumer Electronics:** LED displays and office equipment (printers/copiers). * **Medical Devices:** Diagnostic equipment and monitoring screens. --- ### ## Mating Information To use this part effectively, it must be paired with the correct female housing: * **Compatible Socket Housing:** DF11-28DS-2C * **Crimp Terminals:** DF11-22SC (22 AWG), DF11-2428SC (24-28 AWG), or DF11-30SC (30 AWG).
