305-040-500-278

Edgeboard Connectors Overview

The EDAC 305-040-500-278 is a standard card edge connector header featuring 40 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for panel mount installation at a vertical angle. The contacts are constructed from copper alloy with gold plating, supporting a continuous current rating of 5 A. Termination is achieved via solder eyelets suitable for PCB attachment. The housing is made of green thermoplastic material, accommodating a board thickness of 1.57 mm.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure card edge mating
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Thermoplastic housing provides structural integrity and insulation
• Solder eyelet termination facilitates robust PCB mounting

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact termination style and housing color variations. Ensure compatibility with existing polarizing key requirements, as this series supports between-contact and in-contact keys. Confirm that the selected variant meets the required environmental operating temperature range and voltage ratings for the intended application environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. Ensure the mating card thickness aligns with the 1.57 mm specification. Verify that the 5 A current rating suffices for the circuit load. Consider the inclusion of polarizing keys if mechanical alignment is critical for the assembly process.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options while maintaining consistent pitch and housing dimensions. It is designed for high-reliability applications requiring durable electrical connections in compact form factors.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants sharing the same 40-position count and 3.96 mm pitch. Verify that alternative parts match the dual-row layout and solder eyelet termination style to ensure mechanical fit.
