The **DF1B-R26F** is a specific electronic connector component manufactured by **Hirose Electric (HRS)**. It belongs to the **DF1B series**, which is widely used for wire-to-board and wire-to-wire connections in industrial and consumer electronics. --- ## 1. Component Specification Overview The DF1B-R26F is an ID (Insulation Displacement) type connector housing. Below are the primary specifications: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Hirose Electric (HRS) | | **Series** | DF1B | | **Part Number** | DF1B-R26F | | **Number of Positions** | 26 | | **Pitch** | 2.5mm (0.098") | | **Number of Rows** | 2 (Double Row) | | **Connection Type** | ID (Insulation Displacement) Connector | | **Mounting Type** | Free Hanging (In-Line) | | **Color** | White / Natural | --- ## 2. Key Technical Features ### A. ID (Insulation Displacement) Technology The "R" in the part number signifies that this is an **ID Contact** housing. Unlike crimp connectors where you strip the wire, ID connectors allow the wire to be pressed into a sharp metal slot that "displaces" the insulation to make contact with the conductor. This is significantly faster for mass production. ### B. Double-Row Configuration With **26 positions** arranged in two rows, this connector provides high-density signal transmission while maintaining a relatively small footprint. ### C. Locking Mechanism The DF1B series features a robust locking mechanism that ensures the connector does not vibrate loose, making it suitable for automotive or industrial machinery environments. --- ## 3.
