305-042-520-501

Edgeboard Connectors Overview

The EDAC Inc. 305-042-520-501 is a standard card edge connector from the 305 series, designed for panel mount installation with a vertical orientation. It features 42 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and solder pin termination. It supports 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 female contact configuration for double-sided card edge connections
• Gold-plated semi-bellows contact type ensuring reliable electrical engagement
• Panel mount design with flange featuring top opening and no thread
• Thermoplastic polyester insulation material providing structural stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment board connections
• Automotive electronics module interfaces
• Test and measurement instrument backplanes

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's current ordering guide to confirm exact plating thickness and flange specifications. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm before integration. Confirm that the vertical panel mount style aligns with the mechanical enclosure design requirements.

Edgeboard Connectors Selection Notes

Select this component when a high-density 42-position connection is required with a 3.96 mm pitch. The dual-row layout maximizes I/O capacity within a compact footprint. The gold plating offers superior corrosion resistance compared to tin alternatives, suitable for environments demanding long-term reliability without maintenance.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in handling various card thicknesses and its robust mechanical design. The 305 series is widely used in applications where secure, high-current connections are necessary for double-sided circuit boards.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching position counts and pitch, such as 305-042-520-202 or 305-042-521-202, provided the mounting style and termination type remain consistent.
