Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 32-position dual-row configuration and gold plating specifications. Confirm compatibility with the intended PCB thickness range of 0.054 to 0.070 inches. Ensure the application environment falls within the specified -40°C to 105°C operating temperature limits. Check for RoHS3 compliance requirements if applicable to your manufacturing standards. Validate that the panel mount vertical style aligns with your assembly design constraints.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with polarizing key acceptance is required. Consider the 5A continuous current rating for power distribution needs. Evaluate the 1800VACrms insulation rating for high-voltage isolation applications. Choose based on the need for flush mounting with top openings and solder lug termination. Ensure the 0.156-inch pitch matches the target circuit board layout dimensions.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various contact terminations, mounting options, and row configurations. The series supports multiple card guide solutions and high-temperature insulators.
