The **DF4-28DP-2C** is a specific connector component manufactured by **Hirose Electric Co Ltd**. It belongs to the DF4 series, which is widely known for its high-density packaging and reliability in board-to-wire connections. --- ### 1. General Specifications The part number represents a double-row, 2.0mm pitch connector housing. Below are the core technical parameters: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Hirose Electric (HRS) | | **Series** | DF4 | | **Part Number** | DF4-28DP-2C | | **Connector Type** | Receptacle Housing (Crimp) | | **Number of Positions** | 28 Positions | | **Number of Rows** | 2 Rows (14 pins per row) | | **Pitch (Spacing)** | 2.00mm (0.079") | | **Mounting Type** | Free Hanging (In-Line) | --- ### 2. Physical & Material Properties The housing is designed to be lightweight yet durable, often used in internal wiring for consumer electronics and industrial equipment. * **Color:** Typically Black or Milky White (Standard Polyamide). * **Material:** UL94V-0 Rated Polyamide (Nylon). * **Locking Mechanism:** Friction lock (ensures secure mating without the bulk of large mechanical latches). * **Termination:** Requires crimp contacts (purchased separately, typically the **DF4-2428PCF** or similar series). --- ### 3. Electrical Characteristics These connectors are designed for low-to-medium power signals. * **Current Rating:** 1A to 3A per pin (depending on the wire gauge used). * **Voltage Rating:** 250V AC/DC. * **Contact Resistance:** 30 mΩ Max. * **Insulation Resistance:** 1000 MΩ Min. --- ### 4. Key Applications Because of the **2.0mm pitch**, the DF4-28DP-2C is smaller than standard 2.54mm (0.1") headers, making it ideal for: * LCD panels and display modules. * Office automation equipment (printers, scanners). * Internal power and signal routing in medical devices. * Handheld industrial terminals. --- ### 5. Part Number Breakdown Understanding the Hirose naming convention for this part: * **DF4**: The series name. * **28**: Total number of positions (pins). * **DP**: Double row, Plug (or housing in this context). * **2**: 2.0mm pitch. * **C**: Crimp case. ---
