305-048-555-278

Edgeboard Connectors Overview

The EDAC Inc. 305-048-555-278 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features a dual-row configuration with 48 positions and a contact spacing of 3.96 mm (0.156 inches). The row spacing is 3.56 mm, accommodating printed circuit boards with a nominal thickness of 1.57 mm. The contacts are made of copper alloy with gold over nickel plating to ensure reliable conductivity. Rated for 5 A current at +105°C maximum operating temperature, it utilizes a solder pin termination type.

Edgeboard Connectors Feature Summary

• Vertical panel mount design for secure structural integration
• Dual-row female contact configuration for high-density connections
• Gold over nickel plated copper alloy contacts for corrosion resistance
• Thermoplastic insulator body supporting standard PCB thicknesses

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Embedded computing board interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact physical dimensions and termination style. Ensure compatibility with the target PCB edge thickness of 1.57 mm before procurement. Confirm that the gold over nickel contact finish meets the environmental requirements for the intended application environment.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for double-sided edge cards. The 3.96 mm pitch suits applications needing robust mechanical retention without requiring surface-mounted footprints. Consider the 5 A current rating and -40°C to +105°C temperature range for operational suitability in industrial settings.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides various mounting styles including panel mount and free-hanging options. The series is characterized by its .156 inch contact spacing and low-profile insulator bodies. It serves as a standardized interface for connecting edge-board modules to host systems in modular electronic architectures.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-048-500-201 for different mounting styles or 305-054-556-278 for higher position counts. Verify mechanical fit and electrical ratings before substituting with components from other manufacturers.
