305-012-500-558

Edgeboard Connectors Overview

The EDAC Inc. 305-012-500-558 is a standard card edge connector from the 305 Series, designed for dual female termination. It features 12 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). Contacts are gold-plated copper alloy, rated for 5 A current. The insulator body is green thermoplastic polyester, providing low profile construction.

Edgeboard Connectors Feature Summary

• Dual edge female termination configuration for secure board insertion
• Gold-plated contacts ensure reliable electrical conductivity
• Low profile insulator body design minimizes vertical space requirements

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing modular board architectures
• Test and measurement devices needing high-density connections

Edgeboard Connectors Procurement Notes

Verify that the target application requires a dual-edge female connector rather than single-edge or male variants. Confirm the PCB thickness matches the 0.062-inch specification to ensure proper retention. Check for RoHS compliance requirements if operating in regulated regions. Ensure the mounting style aligns with the panel or PCB mount needs of the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a 12-position dual-edge interface is necessary. The 3.96 mm pitch suits applications where standard spacing is preferred over finer geometries. Consider the 5 A rating against the maximum expected load per contact. Evaluate the green insulator color for visual identification purposes within complex assemblies.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various position counts and termination styles. The series is characterized by its reliability in harsh environments and standardized dimensions. The 305-012-500-558 specifically addresses the need for a compact, dual-sided connection point for mid-sized circuit boards.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 12-position count, 3.96 mm pitch, and dual female termination. Verify that any alternative maintains the same 0.062-inch board thickness acceptance. Cross-reference insulation material properties and temperature ratings to ensure environmental compatibility.
