305-048-556-278

Edgeboard Connectors Overview

The EDAC Inc. 305-048-556-278 is a standard card edge connector designed for panel mount applications with a vertical orientation. It features a dual-row configuration providing 48 positions with a 3.96 mm pitch. The connector utilizes gold-plated copper alloy contacts and a thermoplastic insulator body, rated for 5 A current and 5 GOhms insulation resistance. It supports PCB thicknesses of 1.57 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row vertical panel mount design for secure board insertion
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Thermoplastic housing provides structural integrity and electrical isolation

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating thickness and material specifications. Ensure compatibility with the target printed circuit board thickness of 1.57 mm before procurement. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements of the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a 48-position dual-row interface is required with a 3.96 mm spacing. The vertical panel mount style is suitable for chassis-mounted applications where the card edge inserts perpendicularly. Consider the 5 A current rating and operating temperature limits to ensure suitability for the intended electrical load and environmental conditions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, all sharing a consistent 3.96 mm contact spacing. The 305-048 variant specifically addresses applications requiring a high-density connection point in a robust industrial-grade package.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts having identical 48-position dual-row configurations and 3.96 mm pitch. Verify mechanical dimensions and pinout compatibility before substituting.
