Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm the exact contact count and termination style required for the design. Ensure the selected variant matches the necessary voltage ratings and environmental specifications. Cross-reference the manufacturer datasheet for precise mechanical dimensions before finalizing procurement orders to avoid integration errors.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface with 3.96 mm pitch is required for 1.57 mm thick boards. Consider the 5 A current rating and 1800 VACrms insulation capability for appropriate electrical isolation. Evaluate the need for polarizing key compatibility if mechanical locking against mating cards is essential for the assembly stability.
