Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm contact finish and housing material specifications. Ensure the target printed circuit board thickness falls within the specified operational range of 0.051 to 0.071 inches for proper engagement. Confirm RoHS compliance status if required by project regulations before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge interface with fine 1.27mm pitch is required. The design accommodates non-specified dual-edge cards, offering flexibility in mating board types. Consider the operating temperature range and mounting style compatibility with the host assembly during the initial design phase to ensure mechanical fit.

Edgeboard Connectors Part Context

This part belongs to the EDAC 302 series of standard card edge connectors. The series is characterized by its compact profile and versatile mounting options for various electronic assemblies.
