305-024-500-204

Edgeboard Connectors Overview

The EDAC Inc. 305-024-500-204 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 24 positions with a 3.96 mm (0.156 inch) pitch and accepts PCBs with thicknesses between 1.37 mm and 1.78 mm. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin (0.25 µm) plating thickness to ensure reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, providing high insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features semi-crimped contact type for robust mechanical retention
• Utilizes gold-plated copper alloy contacts for corrosion resistance
• Designed for vertical panel or PCB mount installation styles

Edgeboard Connectors Applications

• Industrial control systems requiring polarized card edge connections
• Telecommunications equipment interface modules
• Test and measurement instrument backplanes
• Automotive electronics sub-assemblies

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, pitch, and mounting style compatibility. Ensure that the polarizing key requirements match the system design, as this connector supports both between-contact and in-contact configurations. Confirm RoHS compliance status and environmental ratings prior to integration into final assemblies.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with polarizing key capability is required. The 3.96 mm pitch and 24-position configuration suit applications needing moderate density. Verify that the target PCB thickness falls within the 1.37 mm to 1.78 mm range. Consider the 5 A current rating and 1800 VACrms dielectric strength for electrical safety margins in the design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for their versatility in accepting various polarizing keys. The series offers multiple position counts and mounting options, catering to diverse electronic interconnect needs. The 305-024-500-204 specifically addresses applications requiring a 24-position dual-edge interface with robust mechanical and electrical specifications.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or mounting styles. Cross-reference with other manufacturers' card edge connectors only if pitch, current rating, and polarizing key compatibility are strictly matched.
