305-052-520-278

Edgeboard Connectors Overview

The EDAC Inc. 305-052-520-278 is a standard card edge connector from the 305 Series, designed for dual-edge board insertion. It features 52 positions with a 3.96 mm (0.156 inch) pitch and a 3.56 mm row spacing. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic housing. Rated for 5 A current, it supports panel mounting in a vertical orientation with solder pin termination. The unit operates within a temperature range of -40°C to +105°C and maintains an insulation resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm compatibility with target PCB thicknesses and mating requirements. Ensure that sourcing channels provide genuine components with traceable manufacturing records. Cross-reference technical specifications such as contact plating and thermal ratings prior to integration to prevent performance discrepancies in final assembly processes.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required for panel-mount applications. The 52-position count suits designs needing moderate I/O density. Verify that the target circuit board thickness aligns with the connector's mechanical constraints. Consider the vertical orientation and solder pin termination method during layout planning to ensure proper physical integration.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which offers various mounting options and position counts. The series is characterized by its robust construction and standardized dimensions, facilitating interchangeability within compatible systems. The specific model represents a mid-range position count variant optimized for vertical panel installation.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 Series models with matching 3.96 mm pitch and dual-row configurations, such as the 305-050-520-278 or 305-052-520-207, provided they meet identical electrical and mechanical specifications.
