## Overview of DF1B-R26 The **DF1B-R26** is a specific electronic connector component manufactured by **Hirose Electric Co., Ltd.** It belongs to the **DF1B series**, which is widely recognized for its versatility in wire-to-board and wire-to-wire connections. The "R26" suffix specifically denotes its compatibility with **26 AWG** (American Wire Gauge) wires and identifies it as an **ID Contact** (Insulation Displacement Contact). --- ### Technical Specifications | Property | Specification | | :--- | :--- | | **Manufacturer** | Hirose Electric (HRS) | | **Series** | DF1B | | **Part Type** | ID Contact (Socket) | | **Wire Gauge (AWG)** | 26 AWG | | **Pitch** | 2.5 mm | | **Contact Plating** | Tin Plated | | **Current Rating** | Up to 3A (depending on wire) | | **Voltage Rating** | 250V AC/DC | --- ### Key Features * **Insulation Displacement (ID):** Unlike crimp terminals, ID contacts allow the wire to be pushed into a V-shaped slot that cuts through the insulation to make contact with the conductor. This significantly reduces assembly time. * **Discrete Wire Compatibility:** Designed for individual wires rather than ribbon cables. * **High Reliability:** Features a double-slot design for the ID section to ensure a stable electrical connection. * **Standard Pitch:** The 2.5mm pitch is a standard in the industry, making it compatible with various headers. --- ### Comparison: ID Contact vs. Crimp Contact | Feature | DF1B-R26 (ID Contact) | DF1B-2428SC (Crimp Contact) | | :--- | :--- | :--- | | **Assembly Method** | Press-fit (Displacement) | Mechanical Crimp | | **Speed** | Faster for mass production | Slower (requires stripping) | | **Tooling** | ID tool/Press | Crimping tool | | **Wire Prep** | No stripping required | Stripping required | --- ### Common Applications 1. **Industrial Equipment:** Control panels and internal wiring. 2. **Consumer Electronics:** Power supply units and signal routing. 3. **Office Automation:** Printers and scanners where high-density wiring is required.
