Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact mechanical dimensions and plating specifications. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm that the M3 threaded insert mounting style aligns with the chassis design requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for a 40-position interface. The 3.96 mm pitch dictates the necessary PCB trace layout constraints. Consider the vertical mounting orientation and the need for panel-mounting hardware when designing the enclosure structure. Verify thermal operating ranges against the application environment.
