305-020-500-258

Edgeboard Connectors Overview

The EDAC Inc. 305-020-500-258 is a standard card edge connector header within the 305 series. It features 20 positions with a 3.96 mm pitch and supports a 1.57 mm board thickness. The component utilizes gold-plated copper alloy contacts for reliable signal transmission. Rated for 5 A current, it employs solder pin termination for secure attachment. Designed for panel mounting at a vertical angle, the housing is constructed from thermoplastic material to ensure mechanical stability in industrial applications.

Edgeboard Connectors Feature Summary

• Dual row configuration providing 20 connection points
• Gold-plated copper alloy contacts for corrosion resistance
• Vertical panel mount design for space-efficient integration
• Thermoplastic housing ensuring structural integrity

Edgeboard Connectors Applications

• Industrial control system interconnects
• Panel-mounted electronic module connections
• High-reliability communication hardware interfaces
• Test and measurement equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact contact plating thickness and termination style. Ensure compatibility with the target PCB edge thickness of 1.57 mm before procurement. Confirm that the vertical panel mount orientation aligns with the mechanical enclosure design requirements. Cross-reference the 5 A current rating with the actual thermal environment of the application to prevent overheating issues during operation.

Edgeboard Connectors Selection Notes

Select this component when a dual-row header with a 3.96 mm pitch is required for vertical panel mounting. The 20-position count suits moderate-density interface needs. Verify that the application environment stays within the specified temperature range. Consider the solder pin termination method for permanent assembly. Ensure the thermoplastic housing material meets any relevant flammability or chemical resistance standards for the intended deployment scenario.

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. The 305-020-500-258 specifically addresses the need for a 20-position vertical header. It shares common electrical characteristics with other parts in the family but differs in physical dimensions and contact configuration. The series is designed for robust performance in demanding environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers with identical 20-position, 3.96 mm pitch, and vertical panel mount specifications. Verify that alternative headers maintain the same 1.57 mm board thickness tolerance. Ensure replacement components offer equivalent gold plating and 5 A current ratings. Check for matching termination types to avoid rework during installation.
