Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact plating thickness, material composition, and mechanical tolerances. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm RoHS compliance status through manufacturer documentation. Validate that the vertical panel mount style aligns with the enclosure design constraints. Cross-reference the 22-position count with schematic requirements to prevent mismatch errors during assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface is required with a 3.96 mm pitch. The 22-position capacity suits moderate-density applications. Verify that the 5 A current rating meets the circuit load requirements. Ensure the operating temperature range of -40°C to +105°C covers the environmental conditions. Confirm that the vertical orientation fits the available panel space and mating depth constraints.
