Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure that the selected variant matches the required polarizing key compatibility and panel thickness constraints. Cross-reference the datasheet for precise dimensional tolerances before finalizing procurement orders to avoid assembly mismatches.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge configuration is required for higher density connections compared to single-edge alternatives. The 3.96 mm pitch offers a balance between signal count and spacing. Consider the 5 A current rating and 1800 VACrms insulation capability for applications demanding high electrical isolation and power handling within compact panel-mounted enclosures.

Edgeboard Connectors Part Context
