305-040-556-558

Edgeboard Connectors Overview

The EDAC Inc. 305-040-556-558 is a standard card edge connector from the 305 Series, designed for dual-edge board insertion. It features 40 positions with a 3.96 mm (0.156 inch) pitch and a 3.56 mm row spacing. The connector utilizes gold-plated copper alloy contacts rated for 5 A current and supports PCBs up to 1.57 mm thick. Constructed with a green thermoplastic insulator, it offers vertical panel mounting and solder pin termination. Operating temperatures range from -40°C to +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-row configuration with gold-plated contacts for reliable signal transmission
• Vertical panel mount design compatible with standard card edge boards
• Thermoplastic housing provides structural integrity and electrical insulation

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Embedded computing module interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm contact plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm maximum. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements. Cross-reference the 5 A current rating with the actual circuit load to prevent thermal issues during operation.

Edgeboard Connectors Selection Notes

Select this component when a 40-position dual-edge connector with a 3.96 mm pitch is required. The vertical orientation suits panel-mounted applications where space efficiency is critical. The gold plating ensures corrosion resistance in demanding environments. Consider the 5 A rating for power distribution needs within the connector limits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which specializes in high-reliability card edge connectors. The series offers various position counts and mounting styles to support diverse electronic assembly needs. The 305-040 variant specifically addresses applications requiring 40 connection points with robust mechanical retention.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 Series parts with identical pitch and position counts but different mounting styles or plating options. Verify mechanical dimensions and electrical ratings before substitution.
