305-018-556-202

Edgeboard Connectors Overview

The EDAC Inc. 305-018-556-202 is a dual-row card edge connector designed for vertical panel mounting applications. It features 18 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating, it ensures reliable electrical performance within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Vertical panel mount design facilitates secure installation in enclosed chassis environments.
• Gold-plated copper alloy contacts provide durable conductivity and corrosion resistance.
• Low-profile insulator body constructed from thermoplastic polyester for compact integration.

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to ensure correct flange and termination specifications. Confirm that the target PCB thickness aligns with the connector's acceptance range. Check regional distribution restrictions as availability may vary by location. Ensure compliance with RoHS3 and REACH standards required for the intended market deployment.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 0.156-inch spacing is required for vertical panel mounting. Ensure the application environment supports the specified temperature range and current ratings. Verify mechanical clearance for the flush-mount flanges during enclosure design. Compare against alternative series if different board thicknesses or row spacings are necessary for the specific hardware architecture.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors. The series offers various position counts and configurations to support diverse electronic module requirements. Components in this family share common design principles regarding contact material and insulation properties, ensuring consistency across different pin count variants.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or termination styles. Cross-reference compatible parts from other manufacturers only if mechanical dimensions and electrical ratings match precisely. Verify that any replacement maintains the same vertical mounting orientation and flange characteristics.
