305-026-520-578

Edgeboard Connectors Overview

The EDAC Inc. 305-026-520-578 is a standard card edge connector featuring 26 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for board thicknesses ranging from 1.37 mm to 1.78 mm. The connector employs gold-plated copper alloy contacts with a half-beam termination style, rated for 5 A current. It supports vertical panel mounting via solder pin end-type connections.

• Computing hardware expansion slots

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm plating thickness and material specifications. Ensure compatibility with target PCB thickness limits of 1.37 mm to 1.78 mm. Confirm that the vertical panel mount style aligns with mechanical enclosure requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. The 26-position count suits moderate density applications. Verify that the 5 A current rating meets circuit demands. Ensure the vertical mounting style fits the assembly constraints compared to horizontal alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts while maintaining consistent 3.96 mm spacing. The 305 series is engineered for robust industrial environments, providing durable connections through gold-plated contacts and thermoplastic housings.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with different position counts or alternative termination styles. Cross-reference compatible parts within the same series to maintain identical pitch and mounting characteristics.
