305-078-500-501

Edgeboard Connectors Overview

The EDAC Inc. 305-078-500-501 is a standard dual-row card edge connector designed for vertical panel mount applications. It features 78 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts plated with gold, it provides a continuous current rating of 5 A and withstands 1800 VACrms. The insulator body is made of thermoplastic polyester.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Low profile insulator body design for compact integration
• Gold-plated copper alloy contacts ensure reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing high-density dual-row connectivity

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating, termination type, and insulation material before procurement. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the 78-position dual-row configuration matches the required circuit density. Check for availability of compatible polarizing keys if mechanical locking is necessary for the application environment.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for 0.062-inch thick boards. The 3.96 mm pitch suits applications needing moderate pin counts without excessive height. Consider the 5 A current rating for power distribution needs. Verify that the thermoplastic polyester housing meets the environmental temperature requirements of the deployment site.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options. The 305-078 variant specifically addresses high-density interface needs within the family. It utilizes a consistent 3.96 mm spacing across the series for interchangeability with other components in the same ecosystem.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC 305-078-500-512 and 305-078-500-258. These alternatives share the same 78-position count and 3.96 mm pitch but may differ in termination style or housing material. Verify dimensional drawings and electrical ratings before substitution.
