305-080-520-503

Edgeboard Connectors Overview

The EDAC Inc. 305-080-520-503 is a standard card edge connector featuring 80 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 5.08 mm (0.200 inch) row spacing. Designed for vertical panel mount installation, the connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are gold-plated copper alloy, while the insulator body is constructed from thermoplastic material. This component supports a continuous current rating of 5 A and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual female contact configuration designed for mating with double-sided card edge PCBs
• Vertical panel mount orientation providing secure structural integration
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance
• Low-profile insulator body accommodates space-constrained mechanical designs

Edgeboard Connectors Applications

• Industrial control system interface connections
• Telecommunications equipment backplane interconnects
• Medical device internal module assembly
• Consumer electronics board-to-board linking

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm plating specifications and contact count. Ensure the target application requires a 3.96 mm pitch and 1.57 mm board thickness compatibility. Confirm that the dual-row vertical panel mount style aligns with the mechanical enclosure requirements. Cross-reference the manufacturer datasheet for precise dimensional tolerances before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this connector when a high-density 80-position interface is required within a standard 3.96 mm grid. The dual-row layout maximizes pin count per unit width compared to single-row alternatives. Verify that the operating environment remains within the specified temperature range and that the 5 A current rating meets the electrical load demands of the connected circuitry.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and mounting styles to support diverse electronic assembly needs. The 305 series is characterized by its robust thermoplastic construction and standardized spacing, ensuring broad compatibility across multiple industrial and commercial hardware platforms.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models with identical 3.96 mm pitch and 80-position dual-row configurations. Verify mechanical footprint compatibility and electrical ratings before swapping components. Alternative part numbers may vary in insulator color or specific plating thickness but must maintain the core dimensional specifications.
