Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact configuration details. Ensure compatibility with target PCB thickness and polarizing key requirements before procurement. Cross-reference datasheet specifications for electrical ratings and environmental limits to validate suitability for the intended operational environment.

Edgeboard Connectors Selection Notes

Select this component when a 56-position dual-row card edge connector is required for panel mounting. Consider the 3.96 mm pitch and 1.57 mm board thickness constraints. Verify that the application requires polarizing key support and operates within the specified -40°C to +105°C temperature range. Confirm that gold-plated contacts meet corrosion resistance needs.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by robust construction suitable for industrial environments.
