305-076-520-268

Edgeboard Connectors Overview

The EDAC Inc. 305-076-520-268 is a standard card edge connector designed for dual-edge board insertion. It features 76 positions with a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm. Constructed with copper alloy contacts gold-plated for conductivity, it utilizes a thermoplastic insulator body. Rated for 5 A current at +105 C maximum operating temperature, it offers 5 GOhms insulation resistance. The unit employs through-hole solder pin termination and is configured for vertical panel mounting.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodating 1.57 mm PCB thickness
• Gold-plated copper alloy contacts ensuring reliable signal transmission
• Vertical panel mount configuration with solder pin termination

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard board thicknesses
• Automotive electronics applications needing high reliability connectors

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB edge guide dimensions and panel cutout requirements before procurement. Confirm that the 5 A current rating aligns with the application's thermal management capabilities.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided card edge interface is required for 1.57 mm thick boards. The 3.96 mm pitch suits applications needing fewer connections in a compact footprint compared to finer pitches. Verify that the vertical orientation fits within the enclosure constraints and that the panel mount style meets the mechanical stability requirements of the assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and termination styles while maintaining consistent 3.96 mm spacing. The 305 series is widely used in industrial and commercial electronics where reliable interconnection between backplanes and plug-in cards is essential.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 76-position count, 3.96 mm pitch, and dual-edge configuration. Verify that alternative parts support the same 1.57 mm PCB thickness and vertical panel mount style. Cross-reference electrical ratings and termination methods to ensure functional equivalence.
