305-020-556-204

Edgeboard Connectors Overview

The EDAC 305-020-556-204 is a standard card edge connector header featuring 20 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and accepts PCBs with a thickness of 1.57 mm. The contacts are constructed from copper alloy with gold plating, supporting a continuous current rating of 5 A. Designed for panel mounting at a vertical angle, the unit employs solder pin termination. The insulator is made of thermoplastic material, providing an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Dual-row contact arrangement with gold-plated copper alloy terminals
• Vertical panel mount design with solder pin termination

Edgeboard Connectors Applications

• Industrial control systems requiring polarized card edge interfaces
• Electronic modules needing robust 5A current carrying capacity
• Panel-mounted interconnect solutions for standardized PCBs

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact mechanical dimensions and plating specifications. Ensure compatibility with polarizing key requirements if used in constrained spaces. Confirm that the target PCB thickness aligns with the specified 1.57 mm tolerance for reliable contact engagement.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount header is required for dual-row card edge applications. The 3.96 mm pitch suits larger board layouts where high current handling is necessary. Verify that the housing material meets environmental temperature ranges and that the gold plating level satisfies corrosion resistance needs for the operating environment.

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 styles while maintaining consistent electrical characteristics. The 305-020 variant specifically addresses applications requiring twenty signal paths in a compact dual-row format suitable for industrial hardware integration.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series headers sharing the same pitch and row count. Verify mechanical footprint compatibility before substituting. Ensure replacement parts maintain identical current ratings and polarizing key acceptance capabilities.
