305-026-556-204

Edgeboard Connectors Overview

The EDAC Inc. 305-026-556-204 is a dual-row card edge connector designed for vertical panel mounting. It features 26 positions with a 0.156-inch (3.96mm) pitch. The connector utilizes female contacts made of copper alloy, finished with gold plating to ensure reliable signal transmission. It is engineered to accommodate printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches. The housing is constructed from green thermoplastic polyester, providing durability and insulation.

Edgeboard Connectors Feature Summary

• Dual-row configuration for high-density interconnect applications
• Vertical panel mount style with flanged design for secure installation
• Gold-plated female contacts for enhanced conductivity and corrosion resistance
• Compatible with standard board thicknesses within specified tolerance

Edgeboard Connectors Applications

• Industrial control systems requiring robust backplane connections
• Telecommunications equipment utilizing modular card architectures
• Test and measurement instruments needing reliable signal interfaces
• Embedded computing modules requiring secure board-to-board connectivity

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm contact type, mounting style, and termination method. Ensure compatibility with target PCB thickness specifications before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and lead times. Confirm environmental compliance status such as RoHS requirements if applicable to the end application.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface is required for vertical panel mounting. Consider the 0.156-inch pitch constraint relative to adjacent components on the mating board. Evaluate the mechanical stability provided by the flange design against vibration or shock environments. Verify that the gold contact finish meets the electrical performance requirements for the intended signal frequencies and current loads.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series offers various configurations including single and dual rows with different mounting options. The 305-026-556-204 specifically addresses needs for moderate pin counts in industrial and commercial electronic assemblies where reliable, repeatable connections are critical.

Edgeboard Connectors Replacement Considerations

Consult EDAC Inc. directly for verified substitute part numbers. Generic equivalents may not match the precise pitch, flange dimensions, or contact material specifications. Ensure any replacement maintains the same dual-row layout and vertical mounting orientation to fit existing chassis designs.
