## DF1B-R26FA: Part Overview and Specifications The **DF1B-R26FA** is a specialized electronic component belonging to the **DF1B Series** manufactured by **Hirose Electric**. It is specifically designed as an IDC (Insulation Displacement Connector) termination tool or housing component used in wire-to-board interconnect systems. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Hirose Electric (HRS) | | **Series** | DF1B | | **Connector Type** | IDC (Insulation Displacement Connector) | | **Number of Positions** | 26 | | **Pitch** | 2.5 mm | | **Mounting Type** | Cable Mount (ID Type) | | **Wire Gauge (AWG)** | 26 AWG to 28 AWG (typical for the R-suffix) | | **Voltage Rating** | 250V AC/DC | | **Current Rating** | Up to 3A (depending on wire size) | --- ### 2. Functional Description The DF1B-R26FA is a **Socket Housing** designed for discrete wire termination using IDC technology. Unlike crimp connectors that require stripping insulation, the IDC mechanism pierces the insulation to make contact with the conductor, significantly reducing assembly time for 26-position cables. #### Design Features: * **Insulation Displacement:** Allows for high-efficiency wiring. * **Polarization:** The housing is keyed to prevent incorrect insertion into the header. * **Secure Locking:** Features a friction-lock mechanism to ensure vibration resistance once mated to a board header. * **Compact 2.5mm Pitch:** Provides a balance between space-saving and ease of handling. --- ### 3. Compatible Components To create a complete connection, the DF1B-R26FA is typically paired with the following: 1. **Headers:** DF1B Series through-hole or SMT headers (e.g., DF1B-26P-2.5DSA). 2. **Termination Tool:** Hirose specific manual or automatic IDC tools are required to press the wires into the "FA" (Fast Assembly) housing. 3. **Wires:** Standard UL1061 or UL1007 discrete wires within the specified AWG range. --- ### 4. Applications * **Industrial Equipment:** Internal wiring for control panels. * **Consumer Electronics:** Power and signal routing for appliances. * **Office Automation:** Printers and scanners. * **Medical Devices:** Reliable signal transmission between internal PCB modules. ---
