305-076-556-278

Edgeboard Connectors Overview

The EDAC Inc. 305-076-556-278 is a standard card edge connector designed for panel mount applications. It features a dual-row configuration with 76 positions and a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts that are gold-plated, it provides a continuous current rating of 5 A and supports 1800 VACrms insulation voltage. The housing utilizes thermoplastic material, ensuring reliable performance in vertical mounting orientations.

Edgeboard Connectors Feature Summary

Accepts between-contact and in-contact polarizing keys for secure board alignment
Features a low-profile insulator body to minimize overall assembly height
Utilizes gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance

Edgeboard Connectors Applications

Industrial control systems requiring robust card edge interfaces
Telecommunications equipment utilizing high-voltage isolation standards
Panel-mounted electronic assemblies needing polarized connection options

Edgeboard Connectors Procurement Notes

Verify the specific manufacturer part number against official EDAC documentation before procurement. Confirm that the required polarizing key type matches the connector's acceptance specifications. Ensure the target printed circuit board thickness aligns with the 1.57 mm nominal requirement for proper mechanical engagement. Check regional availability status as distribution may be restricted in certain locations.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 76 positions is required. Choose this model if the application demands a 5 A current rating and 1800 VACrms dielectric strength. Consider this part for vertical panel mounting scenarios where a 3.96 mm pitch is necessary. Verify compatibility with existing polarizing key requirements for between-contact or in-contact configurations.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its ability to accommodate polarizing keys and support various board thicknesses. The 305 series typically offers high reliability for industrial and commercial applications requiring secure electrical connections between backplanes and daughter cards.
