305-082-520-504

Edgeboard Connectors Overview

The EDAC Inc. 305-082-520-504 is a standard card edge connector featuring 82 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm (0.140 inch) row spacing. The connector is designed for PCBs with a nominal thickness of 1.57 mm (0.062 inch). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are gold-plated copper alloy, while the housing is constructed from green thermoplastic polyester. It operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided circuit boards
• Low-profile insulator body reduces overall assembly height
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance
• Thermoplastic polyester housing provides structural stability and thermal endurance

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Automotive electronics modules needing high-temperature reliability
• Test and measurement instrumentation with frequent board insertion cycles

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to confirm specific packaging or plating variations. Confirm that the target application supports the 3.96 mm pitch and 1.57 mm board thickness requirements. Ensure compatibility with panel mount or PCB mount styles as specified in the official datasheet. Cross-reference the manufacturer's latest documentation for any updates on material composition or environmental compliance status prior to finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 82 positions is required. The 3.96 mm pitch suits applications where space efficiency is balanced with high pin count needs. Verify that the operating environment stays within the -40°C to +105°C range. Consider the gold plating for environments requiring long-term corrosion resistance. Ensure the mating card edge thickness matches the 1.57 mm specification for proper contact engagement.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and configurations. The series is characterized by its standardized dimensions and reliable performance in industrial settings. The 305-082 variant specifically addresses high-density connection needs. It complements other components in the same family by maintaining consistent mechanical and electrical standards across different pin counts.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series connectors with identical 82-position dual-row configurations. Verify that alternative parts match the 3.96 mm pitch and 1.57 mm board thickness. Check for equivalent current ratings and temperature ranges. Ensure that the mounting style and housing material are compatible with existing assembly processes.
