The **DF1B-R26A** is a specific electronic component from the **Hirose Electric (HRS) DF1B Series**. It is a connector accessory designed to facilitate wire-to-board or wire-to-wire connections, specifically utilizing "ID" (Insulation Displacement) technology. --- ### 1. Key Technical Specifications The following table outlines the core electronic and physical characteristics of the DF1B-R26A: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Hirose Electric Co Ltd | | **Part Series** | DF1B | | **Type** | ID Contact (Socket) | | **Applicable Wire Gauge** | 26 AWG | | **Insulation Diameter** | φ0.9 to 1.2 mm | | **Current Rating** | 3A (depending on wire size) | | **Voltage Rating** | 250V AC/DC | | **Contact Plating** | Tin Plating | | **Packaging** | Reel (for automated termination) | --- ### 2. Functional Description The DF1B-R26A is an **Insulation Displacement Contact (IDC)**. Unlike traditional crimp contacts where the wire must be stripped, IDC contacts feature sharp metal "blades" that pierce the insulation of the wire to make contact with the conductor. #### Key Benefits: * **Labor Efficiency:** Eliminates the need for wire stripping. * **Consistency:** Reduces human error during the termination process. * **High Density:** Designed for a 2.5mm pitch, allowing for compact PCB layouts. --- ### 3. Usage Requirements To use the DF1B-R26A, you must pair it with the appropriate housing and tooling. #### Compatible Components: * **Housing:** Must be used with DF1B series "ID" type socket housings (e.g., DF1B-xS-2.5R). * **Mating Headers:** Connects to DF1B series pin headers (Straight or Right Angle). * **Tooling:** Requires specialized Hirose ID tools (Manual or Automatic) to ensure the wire is pressed into the contact correctly. --- ### 4. Application Examples * **Industrial Automation:** Control panels and internal wiring. * **Consumer Electronics:** Power supply units and signal routing. * **Office Equipment:** Printers and scanners where multi-pin wire harnesses are required.
