KR2542 Series Dual Row SMT Straight Female Header, with a height of 7.1mm, is designed for high performance electronics and incorporates various PCB layouts. Its high current load, low contact resistance, and high insulation resistance ensure signal stability and accuracy. Phosphor bronze contacts are gold plated for corrosion resistance and high conductivity. Operating temperature -40°C to +105°C, adaptable. Ideal for PCB design and manufacturing, supporting the stable operation of electronic products.


  • High-performance connection

Its inline design ensures a solid and reliable connection to the PCB board, providing good electrical conduction performance, helping to minimize signal loss and improve overall system operation efficiency.

  • Highly adaptable

The dual row pin layout increases the number of connection points, making the connector suitable for use in complex circuit designs that require high-density pin connections, while the 7.1mm height facilitates compatibility and layout with other components.

  • High-quality materials

The use of phosphor bronze as the contact material not only ensures good electrical conductivity, but also has high wear and corrosion resistance, extending the service life of the connector. Meanwhile, the optional gold-plated surface treatment further enhances its oxidation and corrosion resistance.

  • Wide Operating Temperature Range

Supporting a wide operating temperature range from -40°C to +105°C, the connector is able to work stably in a variety of extreme environments to meet the needs of a wide range of industrial applications.

  • Easy Installation and Maintenance

The KR2542 Series connectors can be automated during the installation process, greatly improving productivity. At the same time, its standardized design also facilitates subsequent maintenance and replacement.

  • High Reliability

Through strict quality control and testing, the KR2542 Series connectors are able to maintain stable performance over long periods of time, reducing system downtime due to connector failure and improving overall system reliability.
