305-034-521-208

Edgeboard Connectors Overview

The EDAC 305-034-521-208 is a standard card edge connector header featuring 34 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing. Designed for .062 inch (1.57 mm) nominal thickness printed circuit boards, the unit employs gold-plated copper alloy contacts and solder pin termination. The connector supports a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage. Operating temperatures range from -40°C to +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Features a low-profile insulator body constructed from thermoplastic material
• Provides high dielectric strength suitable for demanding electrical environments

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring robust card edge interfaces
• Industrial control systems utilizing standardized PCB thicknesses
• Communication equipment needing reliable dual-row signal transmission

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or verified supply chain channels. Confirm that the specific part number matches the required 34-position dual-row specification and panel mount style. Ensure compliance with RoHS directives if applicable to your manufacturing standards. Cross-reference datasheet revisions to confirm material specifications and plating details before final procurement decisions.

Edgeboard Connectors Selection Notes

Select this connector when a 3.96 mm pitch dual-row interface is required for .062 inch thick PCBs. The 5 A current rating and 1800 VACrms breakdown voltage support high-power applications. Verify that the mounting style aligns with panel installation requirements. Consider the operating temperature range of -40°C to +105°C for environmental suitability in industrial settings.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, a line of standard card edge connectors designed for general-purpose electronic interconnections. The series offers various position counts while maintaining consistent 3.96 mm spacing and .062 inch board thickness compatibility. The 305-034-521-208 specifically provides a 34-position solution within this established family framework.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 34-position dual-row configurations and identical 3.96 mm pitch. Ensure any replacement maintains the same .062 inch board thickness tolerance and gold-plated contact specifications for equivalent performance.
