Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact contact plating thickness and flange characteristics. Ensure compatibility with the target PCB edge thickness specifications before procurement. Confirm RoHS compliance status through the latest certified documentation provided by EDAC Inc. Cross-reference the part number with authorized distributors to validate authenticity and traceability.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row card edge interface with a 3.96 mm pitch is required for vertical panel mounting. Consider the 5 A current rating and -40°C to +105°C operating temperature range for environmental suitability. Evaluate the 1.37 mm to 1.78 mm board thickness tolerance to ensure proper mechanical fit. Compare alternative series if different termination styles or contact counts are necessary for the specific application constraints.
