Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 20-position count and 3.96 mm pitch before ordering. Confirm that the application environment stays within the specified -40 C to +105 C operating temperature range. Ensure the mating PCB thickness is exactly 1.57 mm to guarantee proper contact engagement. Check for RoHS compliance requirements if applicable to your manufacturing standards. Validate that the gold plating specification meets your conductivity needs.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface with a 3.96 mm pitch is required for 20 signals. Consider the 5 A current rating to ensure it supports the load of your circuitry. Choose this model if panel or vertical mounting is preferred over straight PCB mount configurations. Verify that the green thermoplastic housing material aligns with your environmental protection requirements. Ensure compatibility with polarizing keys if mechanical locking is necessary for your assembly.
