305-074-520-202

Edgeboard Connectors Overview

The EDAC Inc. 305-074-520-202 is a standard card edge connector designed for panel mount and through-hole applications. It features solder termination with copper alloy contacts finished in gold. The connector utilizes a polyester thermoplastic insulator body and includes a flush mount flange feature with a floating bobbin design measuring 0.116 inches (2.95mm) in diameter. This component is engineered to accept printed circuit boards with a nominal thickness of 0.062 inches (1.57mm).

Edgeboard Connectors Feature Summary

• Supports both panel mount and through-hole mounting configurations for versatile integration.
• Incorporates a floating bobbin design with a flush mount flange to accommodate board alignment variations.

Edgeboard Connectors Applications

• Medical interconnect solutions such as ventilators and CPAP machines
• Industrial control systems
• Storage devices

Edgeboard Connectors Procurement Notes

Verify the specific contact finish thickness and precise row spacing against the manufacturer's official datasheet before procurement. Ensure that the receiving facility's quality assurance protocols align with EDAC's Total Quality System standards for rigorous inspection. Confirm that the supplier provides traceable documentation matching the part number 305-074-520-202 to guarantee authenticity and compliance with specified material properties.

Edgeboard Connectors Selection Notes

Select this connector when a robust, high-reliability interface is required for medical or industrial environments. The dual-edge gold-plated copper alloy contacts ensure stable electrical performance over time. The floating bobbin mechanism is critical for applications where PCB placement tolerances may vary, reducing mechanical stress on the connection points during operation and assembly.
