306-028-520-102

Overview

The EDAC Inc. 306-028-520-102 is a standard card edge connector from the 306 Series, designed for panel mount installation with a vertical orientation. It features a dual female configuration with 56 positions arranged in two rows of 28 contacts each. The connector utilizes a 3.96 mm (0.156 inch) pitch and is compatible with PCBs having a thickness of 1.57 mm. Contacts are made of copper alloy with gold plating to ensure reliable signal transmission, rated for 5 A current. The housing is constructed from thermoplastic material, providing structural integrity and insulation.

Feature Summary

• Dual-edge female contact design accommodating 56 positions across two rows
• Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
• Thermoplastic housing suitable for vertical panel mounting applications

Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Automotive electronics assemblies needing high-current capable connectors

Procurement Notes

Verify the complete part number including suffixes to confirm specific packaging or environmental ratings. Confirm compatibility with the target PCB thickness of 1.57 mm before integration. Ensure that the mating card edge meets the required dimensional tolerances for the 3.96 mm pitch. Check regional availability as distribution status may vary by location. Cross-reference with official EDAC documentation for any recent specification updates.

Selection Notes

Select this component when a dual-sided card edge interface with a 3.96 mm pitch is required. The 56-position capacity supports complex signal routing in compact panels. Gold plating is essential for environments where oxidation resistance is critical. The vertical panel mount style simplifies assembly in enclosed chassis designs compared to board-mount alternatives.

Part Context

This connector belongs to the EDAC 306 Series, which specializes in standard card edge solutions. The series offers various position counts and pitch options to suit different density requirements. The 306-028-520-102 specifically addresses needs for higher pin counts with a standardized spacing, fitting into broader industrial connector ecosystems.

Replacement Considerations

Direct substitutes within the same series include variants like 306-028-506-102, which shares similar mechanical attributes but may differ in plating or housing color. Verify that any replacement maintains the 3.96 mm pitch and 56-position count to ensure mechanical fit.
