345-056-559-258

Edgeboard Connectors Overview

The EDAC Inc. model 345-056-559-258 is a standard dual-row card edge connector designed for panel mount installation. It features 56 positions with a 2.54 mm (0.100 inch) pitch, accommodating board thicknesses between 1.37 mm and 1.78 mm. The contacts are constructed from copper alloy with 10 µin gold plating and utilize wire wrap termination. Rated for 3 A current, the housing is made of thermoplastic polyester, supporting an operating temperature range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration with wire wrap termination for secure circuit interconnection
• Panel mount right-angle design with integrated card guide rails for stable board insertion
• Thermoplastic polyester insulation providing high dielectric strength and thermal stability

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment signal routing
• Test and measurement instrument interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required termination style and mounting hardware. Confirm that the supplier provides official datasheets confirming the 3 A rating and material specifications. Ensure compatibility with the target PCB thickness range before finalizing orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row interface is required for panel-mounted applications. The wire wrap termination suits environments where soldering is impractical or requires reworkability. Verify that the 56-position count aligns with the signal requirements of the host system.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series of standard card edge connectors. The series offers various position counts and termination options to support diverse electronic assembly needs. The 345-056 variant specifically addresses higher density requirements while maintaining standard mechanical dimensions.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 345 series parts for different position counts. Verify mechanical fit and electrical ratings against alternative manufacturers' dual-row card edge connectors with identical 2.54 mm pitch specifications.
