305-056-556-258

Edgeboard Connectors Overview

The EDAC Inc. 305-056-556-258 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 56 positions with a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Constructed with copper alloy contacts gold-plated for conductivity and a green thermoplastic insulator, it supports a current rating of 5 A. Operating within a temperature range of -40°C to +105°C, it utilizes solder pin termination for secure panel mounting.

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or certified partners. Confirm RoHS compliance status prior to integration. Ensure storage conditions maintain integrity of gold plating and insulator material. Cross-reference ordering suffixes to match specific flange and thread requirements. Validate mechanical dimensions against target PCB specifications before final procurement decisions.

Edgeboard Connectors Selection Notes

Select this model when dual-edge connectivity is required for 1.57 mm thick boards. The 3.96 mm pitch suits high-density layouts needing robust mechanical retention. Gold plating provides corrosion resistance for harsh environments. Verify panel mounting compatibility and thermal limits align with system operational constraints. Consider alternative series if different row spacing or insulation materials are necessary.

Edgeboard Connectors Part Context

Part of the EDAC 305 series standard card edge connectors, offering versatile mounting options including panel installation. The series provides various position counts and termination styles. This specific variant emphasizes dual-edge engagement with solder pin endings, supporting industrial-grade reliability standards and standardized dimensional profiles for broad compatibility.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers sharing the 305 series designation, 56 positions, and identical 3.96 mm pitch. Verify matching flange characteristics, such as embedded installation and top-opening features, to ensure mechanical interchangeability without redesigning mounting hardware.
