305-046-555-278

Edgeboard Connectors Overview

The EDAC Inc. 305-046-555-278 is a standard card edge connector featuring 46 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and supports a maximum board thickness of 1.57 mm. The component employs gold-plated copper alloy contacts with solder pin termination for reliable electrical connection. Designed for panel installation, it offers a vertical mounting style and operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic material, providing an insulation resistance of 5 GOhms and a continuous current rating of 5 A.

Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm compatibility with your PCB stack-up and mating requirements. Ensure that the ordering suffix matches the desired polarization key configuration, as these connectors accept both between-contact and in-contact keys. Cross-reference the datasheet for precise dimensional tolerances and surface finish specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface with a 3.96 mm pitch is required for panel-mounted applications. Consider the 5 A current rating and 1800 VACrms voltage capability for appropriate electrical loading. Verify that the target printed circuit board thickness aligns with the 1.57 mm specification to ensure proper contact engagement and mechanical stability during operation.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its robust construction and versatile mounting options, suitable for various industrial and commercial environments. The 305 series typically features thermoplastic housings and gold-plated contacts, offering reliability in demanding operational conditions while maintaining consistent electrical performance across different position counts.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series variants with matching 46-position dual-row configurations and 3.96 mm pitch. Verify mechanical dimensions and contact plating specifications to ensure interchangeability without modifying the host PCB layout or enclosure design.
