Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact termination style and plating thickness. Ensure compatibility with target PCB thickness tolerances before procurement. Confirm RoHS compliance status through manufacturer datasheets rather than distributor summaries. Validate that the selected variant matches the required panel mounting hardware specifications.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for dual-edge cards. The 3.96 mm pitch suits standard industrial board layouts. Verify that the 1.57 mm board thickness falls within the connector's acceptance range. Consider the 5 A rating for power distribution needs. Ensure the gold contact finish meets environmental durability requirements for the intended application lifecycle.
