305-084-521-204

Edgeboard Connectors Overview

The EDAC Inc. 305-084-521-204 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 84 positions arranged in dual rows with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts and solder pin termination. It accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and employs a thermoplastic polyester insulator body.

Edgeboard Connectors Feature Summary

• Dual row configuration providing high-density connectivity within a low-profile insulator body.
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance.
• Panel mount design with vertical orientation facilitates secure installation on chassis panels.

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-panel connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instruments needing reliable vertical interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 0.062 inches (1.57 mm) before integration. Confirm that the panel mounting holes align with the connector's mechanical dimensions. Check RoHS compliance status against current regulatory requirements for the intended market.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 0.156-inch pitch is required for panel mounting. The 84-position count suits applications needing substantial I/O density in a single connector footprint. Consider the vertical orientation for space-constrained chassis designs where board insertion is perpendicular to the mounting surface.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its use of thermoplastic polyester insulation and gold-plated contacts. The 305 series offers various position counts and row configurations to support diverse electronic assembly needs across industrial and commercial sectors.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series parts with matching 84 positions and 3.96 mm pitch, such as 305-084-520-504 or 305-084-556-278, provided the specific contact type and termination style match the design requirements.
