305-070-556-508

Edgeboard Connectors Overview

The EDAC Inc. 305-070-556-508 is a standard card edge connector header featuring 70 positions with a 3.96 mm pitch. Designed for dual-edge non-specified cards, it accommodates board thicknesses of 1.57 mm. The component utilizes gold-plated copper alloy contacts and solder pin termination. It supports a continuous current rating of 5 A and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys
• Provides high voltage insulation resistance of 1800VACrms

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems
• Dual-edge card insertion applications
• Industrial control hardware requiring polarizing key compatibility

Edgeboard Connectors Procurement Notes

Verify the specific suffix against official EDAC documentation to confirm contact plating and termination style. Ensure the target PCB panel thickness matches the specified 1.57 mm requirement. Confirm that the 70-position layout aligns with the design footprint. Check RoHS compliance status directly from the manufacturer datasheet before final integration.

Edgeboard Connectors Selection Notes

Select this model when a vertical, panel-mount header is required for dual-edge cards. The 3.96 mm pitch suits larger industrial interfaces. Verify that the 5 A current rating meets system load requirements. Consider the gold plating for corrosion resistance in harsh environments compared to tin alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting configurations. The 305-070 variant specifically provides a high-density interface solution for robust mechanical connections in panel-based architectures.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC ordering guide for direct substitutes. Cross-reference compatible parts within the same 305 series family for identical pitch and mounting styles.
