307-020-522-278

Edgeboard Connectors Overview

The EDAC Inc. model 307-020-522-278 is a standard card edge connector classified as an edgeboard connector. It features 20 positions with a dual female contact configuration designed for non-specified board thicknesses. The component utilizes a 0.156-inch (3.96 mm) pitch and incorporates gold-plated contacts to ensure reliable signal transmission. The housing is constructed from green thermoplastic material, providing necessary insulation and mechanical stability for panel-mounted applications.

Edgeboard Connectors Feature Summary

• Dual edge female contact design accommodates double-sided circuit boards
• Gold-plated copper alloy contacts provide corrosion resistance and low contact resistance
• Green thermoplastic housing offers electrical insulation and environmental protection

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify the specific datasheet version for the 307-020-522-278 to confirm exact mating force and retention characteristics. Ensure that the target PCB edge thickness falls within the connector's specified operational range. Confirm that the gold plating thickness meets the required cycle life expectations for the intended application environment before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector is required for vertical panel mounting or chassis integration. The 3.96 mm pitch suits applications needing wider spacing between signals. Verify compatibility with the specific PCB edge guide dimensions. Consider the 5 A current rating per contact when designing power distribution paths within the system architecture.

Edgeboard Connectors Part Context

This part belongs to the EDAC 307 series of standard card edge connectors. The series provides various position counts and mounting styles for diverse electronic assembly needs. The 307-020 variant specifically addresses requirements for twenty-position interfaces. This series is widely used in modular electronic systems where reliable high-density connections are essential.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 307 series connectors with identical 20-position dual female configurations. Verify that alternative parts maintain the same 3.96 mm pitch and gold plating specifications. Cross-reference mechanical drawings to ensure housing dimensions and mounting hole patterns match the existing design constraints.
