305-018-556-278

Edgeboard Connectors Overview

The EDAC Inc. 305-018-556-278 is a standard card edge connector header from the 305 series, featuring an 18-position dual-row configuration with a 3.96 mm pitch. Designed for panel mounting at a vertical angle, it accommodates a board thickness of 1.57 mm. The contacts are constructed from copper alloy and gold-plated, supporting a current rating of 5 A. Termination is achieved via solder pins, ensuring reliable electrical connections in industrial applications.

Edgeboard Connectors Feature Summary

• Dual-row header design providing 18 positions for high-density connectivity
• Gold-plated copper alloy contacts ensure corrosion resistance and stable signal transmission
• Vertical panel mount style facilitates secure installation on chassis panels
• Thermoplastic housing offers mechanical stability across a wide operating temperature range

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing reliable vertical header connections

Edgeboard Connectors Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number 305-018-556-278 with official EDAC documentation. Confirm that the specific suffix matches the required termination type and contact plating specifications. Ensure compliance with relevant environmental standards such as RoHS before integration into final assemblies to maintain supply chain integrity.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row, 18-position interface with a 3.96 mm pitch is required. It is suitable for applications demanding vertical panel mounting and a 1.57 mm board thickness compatibility. Consider the 5 A current rating and gold-plated contacts for environments requiring durable, low-resistance connections without the need for surface-mount termination methods.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of card edge connectors, which are characterized by their 3.96 mm pitch and versatile mounting options. The series includes various position counts and row configurations, catering to diverse electronic assembly needs. As a standard header, it complements mating card edge connectors to form secure electrical pathways in modular hardware designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variants with different position counts or termination styles, such as the 305-018-556-504. Verify dimensional compatibility and electrical ratings before substitution. Alternative manufacturers may offer similar pitch and row configurations, but pin alignment and housing dimensions must be validated against original equipment specifications.
