306-028-521-112

Overview

The EDAC Inc. 306-028-521-112 is a dual-edge female card edge connector designed for panel mounting applications. It features 56 positions with a contact spacing of 0.156 inches (3.96mm). The connector utilizes cantilever contacts made from copper alloy, finished with a gold plating thickness of 10.0µin (0.25µm) to ensure reliable signal transmission. The insulator body is constructed from thermoplastic polyester and is colored green. It accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm), operating within a temperature range of -40°C to 105°C.

Feature Summary

• Dual-edge configuration with cantilever contact type for secure board insertion
• Gold-plated copper alloy contacts providing corrosion resistance and conductivity
• Panel mount installation with low-profile insulator body design

Applications

• Industrial control systems requiring robust card edge interconnects
• Communication equipment utilizing standard PCB thicknesses
• Consumer electronics assemblies needing reliable dual-sided connections

Procurement Notes

Verify the specific part number against official EDAC documentation to confirm compatibility with target PCB thickness and mounting requirements. Ensure that the ordering suffix matches the desired termination style and packaging specifications. Cross-reference the manufacturer's latest datasheet for any updates on material composition or environmental compliance status prior to procurement.

Selection Notes

Select this component when a dual-edge connector with 0.156-inch spacing is required for panel-mounted applications. Consider the 0.062-inch nominal board thickness compatibility and the operating temperature range of -40°C to 105°C. Evaluate the need for gold-plated cantilever contacts for durability in high-cycle insertion environments compared to other contact types.

Part Context

This component belongs to the EDAC 306 series of edgeboard connectors, which are engineered for general-purpose electronic interconnections. The series offers various pin counts and spacing options to accommodate different circuit board densities. The 306 series is characterized by its reliability in industrial and commercial applications, providing stable electrical performance across specified thermal ranges.

Replacement Considerations

Consult official EDAC substitution guides for direct replacements. Verify that alternative parts match the 0.156-inch spacing, 56-position count, and dual-edge female configuration. Ensure mechanical dimensions and mounting styles are compatible with existing panel cutouts and PCB layouts.
