Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to ensure correct contact plating thickness and housing color specifications. Confirm that the required board thickness falls within the accepted tolerance range of 1.37 mm to 1.78 mm for proper mechanical engagement. Cross-reference the series designation to ensure compatibility with existing mating card edge layouts.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with a 3.96 mm pitch is required for panel-mounted applications. Ensure the design accommodates the vertical orientation and solder pin termination method. Verify that the thermal environment remains within the specified operating limits and that the current load does not exceed the rated capacity for the selected contact configuration.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides standard card edge connectors for various industrial and commercial applications. The series offers multiple position counts and row configurations to support diverse board-to-board connectivity needs.
