Overview

The EDAC Inc. 306-028-421-112 is a dual female edge connector from the 306 series, designed for panel mount applications. It features 56 positions arranged in two rows of 28 contacts each, with a 0.156-inch (3.96mm) spacing. The connector utilizes tin-plated cantilever beam contacts made of copper alloy, housed in green thermoplastic polyester insulation. It supports card thicknesses between 0.054 and 0.070 inches and operates within a temperature range of -40°C to 105°C.

Feature Summary

Dual row configuration providing high-density interconnection capabilities
Cantilever beam contact design ensuring reliable board engagement
Thermoplastic polyester housing for thermal stability

Applications

High-density electronic equipment interconnections
Panel-mounted circuit board interfaces
Industrial control system backplanes

Procurement Notes

Verify that the specific ordering suffix matches the required contact plating and housing color specifications. Confirm that the mounting hole dimensions align with the panel cutout requirements. Ensure the selected variant meets the necessary environmental compliance standards for the intended deployment region.

Selection Notes

Select this component when a dual-sided edge connector with 0.156-inch spacing is required. Consider the tin plating option for cost-effective applications where gold plating is not strictly necessary. Evaluate the mechanical fit against the target PCB edge thickness constraints before finalizing the design integration.

Part Context

This part belongs to the EDAC 306 series of edgeboard connectors, which are characterized by their robust construction and versatile mounting options. The series offers various pin counts and spacing configurations to accommodate different density requirements in industrial and commercial electronic assemblies.

Replacement Considerations

Direct substitutes include other EDAC 306 series parts with identical 56-position dual female configurations and 0.156-inch spacing. Verify compatibility regarding contact material and plating type when considering alternative manufacturers.
