305-064-556-278

Edgeboard Connectors Overview

The EDAC Inc. 305-064-556-278 is a standard card edge connector header featuring 64 positions arranged in a double-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing, designed to accept printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component employs gold-plated copper alloy contacts and solder pin termination for secure electrical connections. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

Double-row header design accommodating standard 0.062-inch thick PCBs
Gold-plated copper alloy contacts ensure reliable conductivity
Vertical panel mount style with solder pin termination

Edgeboard Connectors Applications

Industrial control systems requiring robust board-to-board connectivity
Test and measurement equipment interfaces
General-purpose electronic assemblies needing high-density connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact plating thickness and housing material variations. Ensure compatibility with existing panel mounting hardware and PCB slot dimensions before procurement. Cross-reference the RoHS compliance status with the latest regulatory documentation provided by EDAC Inc. for your target market.

Edgeboard Connectors Selection Notes

Select this connector when a vertical, double-row interface is required for 0.062-inch thick boards. The 3.96 mm pitch suits applications needing fewer pins per unit length compared to finer pitches. Confirm that the 5 A current rating meets the system's power distribution requirements and that the operating temperature range aligns with the environmental conditions of the final assembly.
