305-046-556-578

Edgeboard Connectors Overview

The EDAC Inc. 305-046-556-578 is a standard card edge connector header from the 305 Series, designed for vertical panel mounting applications. This dual-edge female connector features 46 positions with a precise pitch of 3.96 mm (0.156 inches). It utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and corrosion resistance. The unit supports a current rating of 5 A and accommodates PCBs with a thickness of 1.57 mm. Constructed with thermoplastic insulation, it operates within a temperature range of -40°C to +105°C and provides an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure board insertion
• Gold-plated copper alloy contacts for enhanced conductivity
• Vertical panel mount style for stable structural integration

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 datasheet to confirm plating thickness and material specifications. Confirm that the target application requires the 3.96 mm pitch and 1.57 mm board thickness compatibility. Ensure environmental conditions remain within the specified -40°C to +105°C operating range for long-term reliability.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection with 46 positions is required in a vertical orientation. The 3.96 mm pitch allows for broader trace spacing compared to finer pitches, reducing manufacturing complexity. The gold plating is suitable for environments requiring low contact resistance without frequent mating cycles.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various position counts and mounting styles. It shares common electrical characteristics with other models in the series, such as the 5 A rating and thermoplastic housing. The specific model number defines the unique combination of 46 positions and dual-edge contact geometry.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 46-position count, 3.96 mm pitch, and vertical panel mount style. Verify that alternative connectors support the same 1.57 mm PCB thickness and dual-edge interface requirements to maintain mechanical fit.
