Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required position count and pitch specifications before procurement. Confirm compliance with RoHS3 and REACH regulations as indicated in official documentation. Ensure the ordering suffix aligns with the desired contact plating and housing color requirements. Cross-reference the datasheet for exact mechanical dimensions to guarantee compatibility with the target enclosure and PCB layout constraints.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row interface is required for vertical panel mounting applications. The 3.96 mm pitch accommodates standard board thicknesses while maintaining robust electrical performance. Consider the 5 A current rating and wide operating temperature range for demanding environments. Verify that the non-specified dual-edge card type matches the design of the mating PCB edge connector for proper engagement.
