305-056-556-512

Edgeboard Connectors Overview

The EDAC Inc. 305-056-556-512 is a standard card edge connector from the 305 series, designed for vertical panel mount applications. It features a dual female configuration with 56 positions and a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts and a thermoplastic polyester insulator body. It accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and offers a continuous current rating of 5 A.

Edgeboard Connectors Feature Summary

• Vertical panel mount design for secure installation
• Dual female contact configuration for board insertion
• Gold-plated copper alloy contacts for reliable conductivity
• Compatible with polarizing keys for alignment

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation panels
• Automotive electronic module interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact plating thickness and flange characteristics. Confirm compatibility with the target PCB thickness of 1.57 mm to ensure proper mechanical engagement. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the selected variant supports the necessary current rating for the application load.

Edgeboard Connectors Selection Notes

Select this component when a high-density, double-sided card edge interface is required for panel-mounted assemblies. The 3.96 mm pitch allows for substantial trace spacing compared to finer pitches. Consider the 5 A current rating for power distribution needs. Verify that the vertical orientation fits within the enclosure constraints and that the panel cutout dimensions align with the connector's flange specifications.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides standard card edge connectors for various industrial applications. The series offers multiple position counts and mounting styles to accommodate different board densities. The 305-056-556-512 specifically addresses the need for a 56-position interface with durable metal contacts and stable insulation properties for long-term reliability in demanding environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching pin counts and pitch, such as 305-056-556-504 or 305-056-556-568, provided the flange and termination details are identical. Cross-brand replacements require verification of pitch, board thickness tolerance, and current rating to maintain electrical and mechanical integrity.
