305-074-500-268

Edgeboard Connectors Overview

The EDAC Inc. 305-074-500-268 is a standard card edge connector designed for vertical panel mount applications. It features 74 positions arranged in a dual row configuration 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 current at an insulation resistance of 5 GOhms. It supports 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

• Vertical panel mount design with flush mounting flange featuring top opening and threaded inserts
• Dual row contact arrangement with gold plating on copper alloy terminals
• Thermoplastic polyester insulation providing high dielectric strength

Edgeboard Connectors Applications

• Rack and panel interconnection systems

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against manufacturer documentation to confirm exact flange and termination specifications. Ensure compatibility with target PCB thickness limits before integration. Cross-reference official datasheets for environmental compliance status and mechanical drawing dimensions to validate fitment requirements.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required for panel-mounted installations. Consider the 74-position count and vertical orientation relative to available chassis space. Confirm that the operating temperature range meets system thermal demands and that the gold contact finish satisfies signal integrity needs.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options for robust electronic interconnections.
