305-066-521-202

Edgeboard Connectors Overview

The EDAC Inc. 305-066-521-202 is a standard card edge connector receptacle from the 305 series. It features 66 positions with a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. Designed for .062 inch (1.57 mm) nominal thickness printed circuit boards, this dual female connector utilizes gold-plated copper alloy contacts rated for 5 A current. The housing is constructed from thermoplastic polyester, offering a low-profile body suitable for panel mount applications.

Edgeboard Connectors Feature Summary

• Dual female configuration providing 66 connection positions
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Low-profile insulator body accommodates space-constrained designs
• Thermoplastic polyester housing provides structural stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing high-density I/O
• Computing hardware modules with specific form factor requirements

Edgeboard Connectors Procurement Notes

Verify the manufacturer part number against official EDAC documentation to confirm compatibility with your specific PCB stack-up and mating header requirements. Ensure that the ordering suffix matches the desired termination style and plating specifications. Cross-reference the datasheet for precise dimensional tolerances and environmental operating ranges before finalizing procurement orders to avoid integration issues.

Edgeboard Connectors Selection Notes

Select this component when a 66-position dual-row interface is required for .062 inch thick circuit boards. The 3.96 mm pitch aligns with standard industry card edge profiles. Consider the 5 A current rating and gold plating for durability in high-cycle environments. Verify that the panel mount style fits the enclosure constraints and that the thermoplastic material meets thermal resistance needs for the application.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge solutions. The series offers various position counts while maintaining consistent 3.96 mm spacing. The 305-066-521-202 specifically addresses applications needing moderate density with reliable electrical performance. It complements other series like the 357 by focusing on standard receptacle configurations without flanges.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include parts with identical positioning and pitch but different row counts or termination styles. Verify that any alternative maintains the same .062 inch board thickness acceptance and dual female contact configuration. Consult official cross-reference guides for exact pin-compatible replacements.
