305-064-555-278

Edgeboard Connectors Overview

The EDAC Inc. 305-064-555-278 is a dual-row card edge connector designed for vertical panel mounting. It features 64 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contacts are gold-plated copper alloy, rated for 5 A continuous current and 1800 VACrms insulation voltage. The insulator body is green thermoplastic, supporting an operating temperature range from -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to confirm specific plating thickness, material composition, and packaging details. Confirm compatibility with existing polarizing key requirements if alignment is critical. Check for updated RoHS compliance status and environmental certifications prior to ordering. Ensure that the receiving facility has appropriate handling procedures for sensitive electronic components.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 0.156-inch spacing is required for 0.062-inch thick boards. Consider the 5 A current rating and 1800 VACrms insulation strength for electrical safety margins. Evaluate the vertical panel mount style against available chassis space. Compare alternative series if different contact materials or insulator colors are necessary for specific identification needs.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge connectors for various industrial applications. The series offers multiple position counts and row configurations to accommodate diverse board designs. Components in this family typically feature durable thermoplastic insulators and standardized dimensions to ensure interchangeability within compatible system architectures.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-062-555-278 for similar specifications with different position counts. Verify mechanical fit and electrical ratings before substituting with non-OEM equivalents. Ensure that any replacement maintains the same contact spacing and board thickness acceptance criteria.
