305-026-520-207

Edgeboard Connectors Overview

The EDAC Inc. 305-026-520-207 is a standard card edge connector header featuring 26 positions with a 3.96 mm pitch. It utilizes gold-plated copper alloy contacts and solder pin termination for secure electrical connections. Designed for panel mounting at a vertical angle, this dual-row component accommodates printed circuit boards with a nominal thickness of 1.57 mm. The unit operates within a temperature range of -40°C to +105°C and maintains an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration ensures reliable mating with double-sided card edges.
• Gold-plated copper alloy contacts provide durable conductivity and corrosion resistance.
• Vertical panel mount style facilitates structured integration into chassis enclosures.

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Embedded computing module interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the vertical panel mount orientation aligns with the mechanical design requirements of the final assembly enclosure.

Edgeboard Connectors Selection Notes

Select this component when a robust connection for thicker 1.57 mm boards is required. The 3.96 mm pitch offers wider spacing compared to finer pitches, aiding in high-voltage isolation or ease of manual handling. Verify that the 5 A current rating per contact meets the power distribution needs of the application circuitry.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and row configurations to support diverse board interface requirements. The 305-026-520-207 specifically addresses applications needing a moderate density of 26 positions with industrial-grade durability.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-026-520-201 and 305-026-520-268, differing primarily in housing color or minor packaging variations. Cross-manufacturer replacements require matching the 3.96 mm pitch, 1.57 mm board thickness tolerance, and dual-row vertical form factor.
