Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to ensure correct plating thickness and material specifications. Confirm that the required polarizing key configuration matches the available options for this series. Check RoHS compliance status if environmental regulations apply to the target assembly. Ensure the board thickness specification aligns with the 1.57 mm requirement before procurement.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for dual-edge cards. The 3.96 mm pitch and 40-position count define the interface density. Consider the 5 A current rating and 105°C maximum temperature for thermal management requirements. Verify compatibility with existing polarizing key standards used in the system architecture.
