305-046-556-207

Edgeboard Connectors Overview

The EDAC Inc. 305-046-556-207 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 46 positions in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and solder pin termination. It accommodates board 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-edge female contact design for secure card insertion
• Gold plating on copper alloy contacts for reliable conductivity
• Panel mount installation style with vertical alignment
• Thermoplastic polyester housing for insulation stability

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with target PCB stack-up dimensions before procurement. Confirm RoHS compliance status through current manufacturer declarations as regulatory requirements may evolve over time.

Edgeboard Connectors Selection Notes

Select this component when a 46-position dual-row interface is required with a 3.96 mm pitch. Verify that the mating card thickness falls within the 1.37 mm to 1.78 mm range. Consider the vertical panel mount requirement and solder pin termination method during mechanical integration planning.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of edgeboard connectors, which are standardized for high-reliability applications. The series offers various position counts while maintaining consistent pitch and mounting characteristics. The 305-046 variant specifically addresses mid-range density needs in modular electronic systems requiring robust mechanical retention.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical pitch and row count but different position numbers, such as 305-050-556-207 or 305-048-520-207, provided mechanical fitment allows. Cross-brand replacements require strict verification of pitch, height, and contact geometry.
