346-025-522-604

Edgeboard Connectors Overview

The EDAC Inc. 346-025-522-604 is a single-row card edge connector designed for PCB interconnection. It features 25 positions with a 0.125-inch (3.18mm) pitch and accepts board thicknesses of 0.031 inches. The connector utilizes gold plating on the mating area to ensure reliable signal transmission, while the contacts are constructed from copper alloy with nickel underplating. The insulator material is thermoplastic polyester rated UL 94V-0, providing flame resistance and stability. This component serves as a female connector interface for edge-board applications.

Edgeboard Connectors Feature Summary

• Gold-plated contact surfaces ensure durable electrical connectivity
• Thermoplastic polyester insulator provides UL 94V-0 flame rating
• Single row configuration supports standard edge-card insertion

Edgeboard Connectors Applications

• Edge-board interconnection in electronic assemblies
• PCB mounting for modular circuit interfaces
• Signal routing in industrial control systems

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required pin count and pitch specifications before procurement. Confirm that the insulator color and flange style align with mechanical enclosure constraints. Ensure the supplier provides original manufacturer documentation to validate material composition and UL ratings. Cross-reference the ordering suffix to confirm exact termination and mounting variations.

Edgeboard Connectors Selection Notes

Select this connector when a single-row interface with 0.125-inch pitch is required. Consider the gold plating for corrosion resistance in demanding environments. Evaluate the thermoplastic polyester housing for thermal stability during soldering processes. Ensure the board thickness tolerance matches the connector's design limits for proper retention.

Edgeboard Connectors Part Context

This component belongs to the EDAC 346 Series, which offers various card edge connector options. The series includes multiple row configurations and termination styles. The 346-025-522-604 variant specifically addresses needs for 25-position single-row connections. Other parts in the series may differ in pitch, row count, or insulator materials.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variants like 346-025-522-107 or 346-025-522-612, depending on specific termination or mounting requirements. Verify compatibility by comparing pin count, pitch, and housing dimensions. Ensure any replacement maintains the same UL rating and contact plating specifications.
