About Rectangular Connector Headers

Rectangular headers form the backbone of wired PCB interfaces, providing secure point-to-point connections between circuit boards and external components. Their standardized pitch configurations enable consistent design implementation across multiple product generations. Proper header selection directly impacts signal integrity, assembly efficiency, and long-term system reliability.

Shrouded variants like this SL 70543 model offer critical polarization and physical protection against misalignment and environmental contaminants. The latch fastening mechanism prevents accidental disconnections in high-vibration environments. These features make shrouded headers essential for automotive and industrial applications where operational stability is paramount.

Packaging

Available in protective tube packaging for automated assembly processes. Bulk quantities supported for production runs.
