305-034-521-278

Edgeboard Connectors Overview

The EDAC 305-034-521-278 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 34 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a thermoplastic polyester housing. Rated for 5 A continuous current, it supports panel mount installation with vertical orientation. The unit accommodates PCB thicknesses between 1.37 mm and 1.78 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic polyester insulation providing high dielectric strength and thermal stability
• Vertical panel mount design compatible with standard card edge insertion methods

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating thickness and flange characteristics. Ensure the target application requires the standard 305 series specifications rather than specialized variants. Cross-reference the pin count and pitch requirements with the system design documentation before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 3.96 mm pitch connection is required for non-specified dual-edge cards. Confirm that the mechanical constraints allow for vertical panel mounting and that the operating environment remains within the specified -40°C to +105°C range. Validate that the 5 A current rating meets the circuit load requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts while maintaining consistent electrical and mechanical interfaces. The 305-034-521-278 specifically provides a 34-position solution, fitting into the broader product line alongside other configurations such as 14, 26, and 38 positions.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for direct substitutes with different position counts or flange options. Verify compatibility with existing tooling and PCB layouts when considering alternative part numbers within the same series.
