HRS DF1B-5ES-2.5RC
Product Overview
The DF1B Series is a 2.5mm pitch connector designed for discrete wire connection, compliant with UL/CSA standards. It features innovative Insulation Displacement (ID) and crimping contact technology, allowing for mixed current capacity cables within a single connector, excellent maintainability through replaceable contacts, and high reliability due to protected insulation displacement areas. The series also offers potting headers for waterproof applications and a broad range of variations including single and double row configurations for board-to-cable and in-line connections, with standard tin and gold plating options.
