305-022-520-208

Edgeboard Connectors Overview

The EDAC Inc. 305-022-520-208 is a standard card edge connector from the 305 Series, designed for panel mount applications. It features 22 positions arranged in a dual row configuration with a 3.96 mm pitch. The connector utilizes gold-plated copper alloy contacts and a thermoplastic housing. It supports a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage. The unit accepts between-contact and in-contact polarizing keys for secure mating. Operating temperatures range from -40°C to +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for enhanced connection security
• Dual-row design with gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic housing provides structural integrity and electrical insulation

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring secure card edge interfacing
• Industrial control systems utilizing modular circuit boards

Edgeboard Connectors Procurement Notes

Verify the specific termination style and contact finish against the official datasheet before procurement. Confirm that the polarizing key requirements match the system design. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the part number suffixes to confirm exact physical dimensions and material specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with polarizing key compatibility is required. The 3.96 mm pitch suits standard board thicknesses. Verify that the 5 A current rating meets the load requirements. Consider the panel mount style for fixed installations rather than backplane or PCB mounting scenarios.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which offers various position counts and termination options. The series is characterized by robust construction suitable for demanding environments. Similar models in the series may differ in pin count, such as 18 or 38 positions, but share common design features like the thermoplastic housing and gold contact plating.

Edgeboard Connectors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing polarizing keys and board stack-up dimensions before considering alternative sources.
