Edgeboard Connectors Procurement Notes

Verify the specific manufacturer part number against official EDAC documentation to confirm compatibility with your design requirements. Ensure that the operating environment stays within the specified -40°C to +125°C range. Confirm that the PCB thickness matches the 1.57 mm acceptance criteria. Check for any regional distribution restrictions or supply limitations before finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this component when high-temperature performance is critical for the application. The DAP insulator material provides superior thermal stability compared to standard thermoplastics. The vertical panel mount style is suitable for chassis-mounted interfaces. Verify that the 3.96 mm pitch aligns with the target card edge layout. Consider the 3 A current rating for power distribution needs.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 833 series, which is specifically engineered for high-temperature operations. The series is characterized by its use of DAP insulators and robust metal contacts. It serves as a reliable interface solution for harsh environments where standard connectors might fail due to thermal stress. The 20-position configuration provides a balanced density for various electronic assemblies.
