305-028-556-204

Edgeboard Connectors Overview

The EDAC Inc. 305-028-556-204 is a standard card edge connector from the 305 series, designed for panel mounting with a vertical orientation. It features 28 positions in a dual female configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes copper alloy contacts with gold plating 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 female contact configuration for reliable signal transmission
• Gold-plated copper alloy contacts ensure corrosion resistance
• Panel mount design with flush, unthreaded top-opening flange
• Thermoplastic polyester insulation provides structural stability

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects

• Embedded computing hardware interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to confirm exact flange dimensions and termination styles. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm before integration. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-current capable card edge interface is required for panel-mounted applications. The 3.96 mm pitch offers mechanical stability for larger boards. Consider the vertical mounting style and dual-row layout for dense signal routing needs in industrial or telecom environments where durability is critical.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its use of thermoplastic polyester insulators and semi-crimped contact designs. These connectors are engineered for high reliability in demanding environments, offering consistent performance across various industrial and commercial electronic systems.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or termination options. Verify that any alternative maintains the 3.96 mm pitch and compatible flange specifications to ensure mechanical fit without modification.
