305-028-520-202

Edgeboard Connectors Overview

The EDAC Inc. 305-028-520-202 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual female configuration with 28 positions and a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts with a solder pin termination type. It is rated for 5 A continuous current and operates within a temperature range of -40°C to +105°C. The insulator body is made of thermoplastic polyester, and it accepts printed circuit boards with a thickness between 0.054 and 0.070 inches.

Edgeboard Connectors Feature Summary

• Dual female card edge interface with gold-plated copper alloy contacts
• Thermoplastic polyester insulator body with vertical panel mount design
• Solder pin termination for secure PCB connection

Edgeboard Connectors Applications

• Medical interconnect solutions such as ventilators and CPAP machines
• Ambulance and medical room equipment connections
• General industrial control panels requiring reliable card edge interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required board thickness and polarizing key configurations. Confirm that the gold plating thickness meets application requirements for signal integrity and durability. Check RoHS compliance status if restricted substances are a concern for the target market. Ensure the panel mount style aligns with the mechanical enclosure design constraints.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided card edge connector with 28 positions is required for vertical panel mounting. The 3.96 mm pitch suits applications needing robust electrical connections with high current capacity. Consider the thermoplastic polyester material for environmental stability. Verify that the target PCB thickness falls within the specified acceptance range to ensure proper contact engagement and mechanical stability during operation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and medical electronics. The series offers various position counts and mounting styles to accommodate different system architectures. The 305-028-520-202 specifically addresses needs for moderate density connections with reliable solder pin termination, providing a balance between connectivity density and mechanical robustness for panel-mounted assemblies.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or flange characteristics. Cross-reference with other manufacturers' card edge connectors only if mechanical dimensions and electrical ratings are identical. Verify that any alternative maintains the same dual female configuration and vertical panel mount orientation to ensure interchangeability without redesigning the host enclosure.
