Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact termination style and housing color variations. Ensure that the selected variant matches the required polarizing key compatibility and panel cutout dimensions. Cross-reference the manufacturer's latest ordering guide to confirm availability status and compliance certifications such as RoHS before final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount interface is required for double-sided edge cards. Confirm that the PCB thickness falls within the specified tolerance of 1.57 mm. Evaluate the need for polarizing keys to prevent incorrect insertion. Compare current ratings and voltage withstand capabilities against system requirements to ensure operational safety under maximum load conditions.
