305-058-521-204

Edgeboard Connectors Overview

The EDAC Inc. 305-058-521-204 is a standard card edge connector from the 305 Series, designed for dual-edge board insertion. It features 58 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 housing is green thermoplastic polyester, and it utilizes solder pin termination for panel mount installation.

Edgeboard Connectors Feature Summary

• Dual-row configuration supporting dual-edge PCB insertion
• Gold-plated contacts ensure reliable electrical performance
• Low-profile insulator body design for space-constrained applications

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 58-position count and dual-edge specification. Confirm that the supplier provides original manufacturer documentation to ensure compliance with RoHS standards. Check for any specific handling requirements related to the gold-plated contacts during storage and assembly processes.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 3.96 mm pitch is required. Ensure the target PCB thickness aligns with the 1.57 mm acceptance range. Consider the vertical panel mount style and solder pin termination method for integration into the final assembly design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which offers various mounting options and configurations. The series is characterized by its .156 inch contact spacing and low-profile bodies. This specific model represents a high-density option within the series, providing 58 positions for complex signal routing needs.

Edgeboard Connectors Replacement Considerations

Direct substitutes must maintain the 58 position count, 3.96 mm pitch, and dual-edge interface. Verify compatibility with existing PCB layouts and mounting hardware before switching suppliers or alternative part numbers.
