Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct termination style and flange configuration. Confirm that the selected variant matches the required PCB thickness tolerance and mounting orientation. Cross-reference the part number with the latest datasheet to validate compliance with applicable environmental standards and material specifications before final procurement.

Edgeboard Connectors Selection Notes

Select this connector when a high-density 74-position interface is required for vertical panel mounting applications. Ensure the design accommodates the specified 3.96 mm pitch and allows space for the flush mount flange features. Verify that the target PCB maintains the nominal 1.57 mm thickness to guarantee proper contact engagement and mechanical stability during operation.
