305-048-520-208

Edgeboard Connectors Overview

The EDAC Inc. 305-048-520-208 is a standard card edge connector header featuring 48 positions in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and supports a PCB thickness of 1.57 mm. The component employs gold-plated copper alloy contacts with a solder pin termination type for secure electrical connections. Designed for panel mount installation at a vertical angle, it operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic polyester, providing an insulation resistance of 5 GOhms and a current rating of 5 A.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided card edge PCBs for high-density signal routing.
• Vertical panel mount style ensures stable mechanical integration into chassis or enclosure structures.
• Gold-plated copper alloy contacts provide reliable conductivity and corrosion resistance over repeated mating cycles.

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 ensure compatibility with required PCB thickness and termination styles. Confirm that the thermoplastic housing material meets environmental standards for the intended operating temperature range. Cross-reference the 48-position dual-row layout with mechanical constraints before finalizing procurement specifications.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-current connection is required for thick PCBs up to 1.57 mm. The 3.96 mm pitch offers spacing advantages for high-voltage isolation compared to finer pitches. Ensure the application environment remains within the specified -40°C to +105°C operational limits to maintain insulation integrity and contact performance.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its heavy-duty construction and suitability for demanding industrial environments. The 305 series provides various position counts and pitch options, with this specific model focusing on the 48-position dual-row format for substantial I/O requirements.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series headers with identical 48-position dual-row configurations and 3.96 mm pitch. Verify mechanical dimensions and mounting hole patterns to ensure interchangeability without modifying the host panel structure.
