305-066-520-278

Edgeboard Connectors Overview

The EDAC Inc. 305-066-520-278 is a standard card edge connector designed for dual-edge circuit board interfaces. It features 66 positions arranged in two rows with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts, it utilizes gold plating and solder pin termination. The housing is made of thermoplastic material, supporting panel mount installation at a vertical angle.

Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm compatibility with target PCB thickness and mounting requirements. Ensure that the gold plating specifications meet the operational environment standards. Cross-reference the series 305 ordering guide for accurate mechanical dimensions and mating partner details before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 66 positions is required. The 3.96 mm pitch and 1.57 mm board thickness compatibility are critical constraints. Consider the vertical panel mount style and solder pin termination method during mechanical integration planning. Verify thermal operating ranges if used in high-temperature environments.

Edgeboard Connectors Part Context

This component belongs to the EDAC Series 305 family of standard card edge connectors. The series offers various position counts and configurations tailored for diverse electronic interconnection needs. The 305-066 variant specifically addresses applications needing higher density connections within the standard 3.96 mm pitch framework, maintaining consistent mechanical and electrical characteristics across the product line.

Edgeboard Connectors Replacement Considerations

Consult the EDAC Series 305 ordering guide for direct substitutes with different position counts or housing variations. Ensure any replacement maintains the 3.96 mm pitch and 1.57 mm board thickness acceptance to guarantee mechanical fit.
