discrete wire connector HRS DF1B-5EP-2.5RC 25mm pitch with replaceable contacts and insulation displacement
DF1B Series: 2.5mm Pitch Connector for Discrete Wire Connection (UL/CSA Standard Compliant)
The DF1B Series is a versatile 2.5mm pitch connector designed for discrete wire connections, offering both Insulation Displacement (ID) and crimping contact options. This series allows for mixing cables with different current capacities within a single connector housing, enhancing flexibility. Key features include excellent maintainability through replaceable contacts, high reliability due to protected insulation displacement areas, and cost-effective ID connection using existing crimping machines with an applicator change. The series also offers potting headers for waterproof applications and a broad range of variations for board-to-cable and in-line connections, with standard tin and gold plating options.
