305-026-521-207

Edgeboard Connectors Overview

The EDAC Inc. 305-026-521-207 is a standard card edge connector from the 305 series, designed for reliable signal transmission in electronic assemblies. This component features a dual-row configuration with 26 positions and a precise pitch of 3.96 mm (0.156 inches). It utilizes gold-plated copper alloy contacts to ensure low resistance and durability. The connector supports a maximum current rating of 5 A and operates within a temperature range of -40°C to +105°C. It employs a solder pin termination method and is housed in a green thermoplastic insulator, suitable for panel mount applications.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided card edges for enhanced connectivity density.
• Gold-plated copper alloy contacts provide corrosion resistance and stable electrical performance over time.
• Thermoplastic housing offers mechanical stability and meets specified insulation resistance requirements.

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact physical dimensions and plating specifications. Ensure compatibility with the target PCB stack-up and mating card thickness before procurement. Confirm availability status through authorized distributors as supply levels may vary by region.

Edgeboard Connectors Selection Notes

Select this model when a 26-position dual-row interface with a 3.96 mm pitch is required. Consider the 5 A current rating and operating temperature limits for thermal management. Verify that the panel mount style aligns with the enclosure design constraints and mounting hole patterns.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and row configurations to support diverse board-to-board connection needs. The 305 series is characterized by its robust construction and standardized dimensions, facilitating integration into modular electronic systems requiring high reliability.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 26 positions and 3.96 mm pitch, such as 305-026-520-207 or 305-026-521-203, provided functional parameters align. Cross-brand replacements require verification of pitch, row count, and mounting style compatibility.
