305-018-520-558

Edgeboard Connectors Overview

The EDAC Inc. 305-018-520-558 is a standard card edge connector from the 305 series, designed for dual-row applications. It features an 18-position configuration with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts that are gold-plated, it supports a current rating of 5 A. The unit utilizes a solder pin termination type and is intended for panel mounting in a vertical orientation.

Edgeboard Connectors Feature Summary

• Gold-plated copper alloy contacts ensure reliable electrical conductivity
• Vertical panel mounting style facilitates structured assembly

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment signal routing
• Automotive electronics module connections
• Medical device internal circuit interfacing

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and insulation ratings. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability status and regional distribution restrictions. Confirm that the vertical mounting orientation aligns with the mechanical design constraints of the final enclosure.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface is required for 18-position signals. The 3.96 mm pitch suits applications needing wider spacing between adjacent traces. Verify that the 5 A current rating meets the power requirements of the connected circuits. Ensure the panel mount requirement matches the system chassis design. Consider the gold plating for environments where corrosion resistance is critical for long-term reliability.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and mounting options. The series is characterized by its standardized dimensions and reliable performance in harsh environments. Similar models within the family differ primarily in the number of positions and specific housing colors or materials, while maintaining consistent electrical characteristics and mechanical interfaces.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series connectors with matching 18-position configurations and identical pitch specifications. Verify that any alternative part maintains the same dual-row layout and vertical mounting angle. Check that the replacement component supports the same PCB thickness tolerance and current rating to ensure functional equivalence without mechanical interference.
