305-038-556-204

Edgeboard Connectors Overview

The EDAC Inc. 305-038-556-204 is a standard card edge connector designed for vertical panel mounting applications. It features a dual female configuration with 38 positions arranged in two rows, providing a total of 76 contact points. The connector utilizes a 0.156-inch (3.96 mm) pitch spacing between contacts and supports printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating, this component ensures reliable electrical performance within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from thermoplastic polyester
• Supports continuous current ratings of 5A and withstands 1800VACrms voltage

Edgeboard Connectors Applications

• Vertical panel mount interconnect systems
• Industrial control module integration
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific pin count and row configuration against your schematic requirements before ordering. Confirm that the target PCB thickness aligns with the specified 1.57mm nominal tolerance to ensure proper mechanical engagement. Check regional distribution availability as stock levels may vary by location. Ensure compliance with RoHS3 specifications if required by your manufacturing standards.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge female connector with a 3.96mm pitch is required for panel-mounted assemblies. The inclusion of polarizing key acceptance distinguishes it from standard variants lacking such alignment features. Consider the 5A current rating and high voltage insulation capabilities for robust industrial environments requiring stable signal transmission over extended temperature ranges.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, all sharing common design principles such as gold-plated copper alloy contacts and thermoplastic insulation. The 305-038-556-204 specifically addresses the need for 38-position connectivity in vertical panel configurations.

Edgeboard Connectors Replacement Considerations

For direct functional substitution, consider the 305-038-556-278 which shares identical electrical and mechanical specifications but may differ in packaging or specific supplier designation. Verify compatibility with existing polarizing key requirements when selecting alternative part numbers within the same series.
