2.5mm pitch connector HRS DF1B-2S-2.5R featuring phosphor copper ID contacts and polyamide insulator
DF1B Series: 2.5mm Pitch Connector for Discrete Wire Connection (UL/CSA Standard Compliant)
The DF1B Series is a 2.5mm pitch connector designed for discrete wire connection, offering innovative Insulation Displacement (ID) and crimping contact technologies. This series allows for mixing cables with different current capacities within a single connector housing, enhances maintainability through replaceable contacts, and ensures high reliability with protected insulation displacement areas. It is compatible with existing crimping machines by simply changing the applicator, eliminating the need for expensive specialized equipment. Potting headers are available for waterproof applications. The series offers broad variations including single and double row configurations for "Board to Cable" and "In-line" applications, with standard tin and gold plating options.
