Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and flange dimensions. Ensure the target PCB design matches the specified 1.37 mm to 1.78 mm thickness range for proper mechanical engagement. Confirm that the required current load does not exceed the 5 A continuous rating under operating conditions.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge interface is required for panel-mounted installations. The 3.96 mm pitch offers a balance between signal density and spacing. Consider the gold plating for corrosion resistance in demanding environments. Verify compatibility with existing polarizing key requirements before finalizing the design.

Edgeboard Connectors Part Context
