305-074-520-207

Edgeboard Connectors Overview

The EDAC Inc. 305-074-520-207 is a standard card edge connector from the 305 Series, designed for panel mounting in a vertical orientation. It features 74 positions with a dual female contact configuration and a 3.96 mm (0.156 inch) pitch. The contacts are gold-plated copper alloy, providing a continuous current rating of 5 A and a dielectric withstand voltage of 1800 VACrms. The housing is green thermoplastic, supporting board thicknesses typically within the series range.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Dual-edge female contact design for robust signal transmission
• Gold-plated contacts ensure reliable conductivity and corrosion resistance

Edgeboard Connectors Applications

• High-density electronic interconnect systems
• Industrial control panels requiring polarized keying
• Vertical board-to-board or board-to-panel connections

Edgeboard Connectors Procurement Notes

Verify the specific insulation material grade and flange dimensions against the official EDAC datasheet before integration. Confirm that the target PCB thickness falls within the mechanical acceptance range to ensure proper contact engagement. Ensure the application environment does not exceed the specified temperature limits or voltage ratings.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count dual-edge connector with polarizing key compatibility is required. The 3.96 mm pitch suits applications needing wider spacing than standard 2.54 mm headers. Verify that the 5 A current rating meets the load requirements and that the vertical panel mount style aligns with the chassis design constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides standardized card edge connectors for various industrial and commercial applications. The series offers multiple position counts and mounting styles, maintaining consistent electrical characteristics such as the 5 A rating and gold plating across variants.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts for different pin counts. Verify that substitute models maintain the same 3.96 mm pitch and dual female configuration to ensure mechanical and electrical compatibility.
