305-056-521-578

Edgeboard Connectors Overview

The EDAC Inc. 305-056-521-578 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 56 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic housing. 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 for secure board alignment
• Dual-edge female contact design ensures reliable signal transmission
• Gold-plated contacts provide corrosion resistance and low contact resistance

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment backplanes
• Medical device circuit boards
• Energy management system interfaces

Edgeboard Connectors Procurement Notes

Verify the specific pin count and row configuration against the target PCB layout before ordering. Confirm that the housing material and color specifications meet environmental requirements. Ensure the solder pin termination type is compatible with the assembly process. Check for any regional distribution restrictions or RoHS compliance documentation needs.

Edgeboard Connectors Selection Notes

Select this model when a 56-position dual-row connector with a 3.96 mm pitch is required. Consider the 5 A current rating and thermal limits for power handling. Verify compatibility with polarizing keys if board positioning is critical. Compare against other 305 series variants for different position counts or housing colors.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and housing options while maintaining consistent electrical performance and mechanical dimensions. It is part of EDAC's broader portfolio of high-quality interconnect solutions for diverse industrial and commercial applications.

Edgeboard Connectors Replacement Considerations

Consult official EDAC documentation for confirmed substitute part numbers. Direct replacements must match the 56-position, dual-row, 3.96 mm pitch specification. Verify that alternative models maintain the same current rating and operating temperature range.
