• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Low profile thermoplastic insulator body suitable for space-constrained panel installations

Edgeboard Connectors Applications

• Industrial control system interface connections
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required mounting hardware and polarizing key configurations. Confirm that the target PCB thickness falls within the specified acceptance range of 1.57 mm nominal. Check regional distribution availability as stock levels may vary by location.

Edgeboard Connectors Selection Notes

Select this component when a robust 40-position connection is required for double-sided edge cards. Ensure the application environment remains within the -40°C to +105°C operational limits. Verify that the 3.96 mm pitch aligns with the existing board layout constraints and that the 5 A current rating meets the signal power requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides various mounting options and contact terminations. The series supports multiple row configurations and high-temperature insulators. It is engineered for reliable performance in demanding electronic assemblies requiring standardized card edge interfaces.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305 Series variants such as 305-040-555-278 or 305-040-555-568 if different housing materials or termination styles are needed. Ensure substitute parts maintain the same 3.96 mm pitch and 40-position count.
