Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB board thickness range of 1.37 mm to 1.78 mm before integration. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements. Cross-reference the 28-position count and dual-row layout with the schematic design to prevent mismatched interface configurations.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-current connection is required for double-sided card edge applications. The 3.96 mm pitch accommodates standard industrial board layouts. Consider the 5 A current rating and wide operating temperature range for demanding environments. Verify that the solder pin termination method matches the assembly process capabilities. Ensure the panel mount style fits the available chassis space constraints.
