305-042-520-268

Edgeboard Connectors Overview

The EDAC Inc. 305-042-520-268 is a standard card edge connector from the 305 series, designed for panel-mounted vertical installation. It features a dual-row configuration with 42 positions and a 3.96 mm (0.156 inch) pitch. The contacts are made of copper alloy with gold plating, rated for 5 A current. The housing is green thermoplastic, supporting board thicknesses between 1.37 mm and 1.78 mm. Operating temperature ranges from -40°C to +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-row female contact design for double-sided card edge connections
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Thermoplastic insulator provides stable mechanical support and high insulation resistance
• Vertical panel mount style with solder pin termination

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment backplanes
• Test and measurement instrumentation
• Automotive electronic modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the official EDAC datasheet to confirm exact physical dimensions and termination type. Ensure compatibility with target PCB card thickness within the specified range. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for double-sided cards. The 3.96 mm pitch suits applications needing higher current capacity than finer pitches allow. Verify that the 42-position count matches the circuit requirements and that the green thermoplastic housing meets environmental constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for durability in harsh environments. The series offers various position counts and mounting styles, serving as a versatile interconnect solution for industrial and commercial electronics where reliable board-to-board or board-to-backplane connections are critical.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers sharing the same 305 series prefix and identical 42-position, 3.96 mm pitch specifications. Verify mechanical footprint and electrical ratings match before substitution.
