Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, contact plating thickness, and housing color specifications. Ensure compatibility with the target PCB edge thickness and panel mounting requirements before procurement. Cross-reference the manufacturer part number with distributor catalogs to confirm current availability status and lead times.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-current card edge interface is required for panel-mounted assemblies. The 3.96 mm pitch accommodates larger gauge traces, while the gold plating offers superior corrosion resistance compared to tin finishes. Consider the dual-row layout for increased I/O density within the specified footprint constraints.
