305-084-521-558

Edgeboard Connectors Overview

The EDAC Inc. 305-084-521-558 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 a dual-edge configuration, utilizing a 3.96 mm (0.156 inch) pitch. The connector accepts non-specified dual-edge cards and employs gold-plated copper alloy contacts to ensure reliable signal transmission. Rated for 5 A continuous current, it utilizes a thermoplastic housing and solder pin termination for secure PCB attachment.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates non-specified card edge boards for versatile integration.
• Gold-plated copper alloy contacts provide corrosion resistance and stable electrical performance.
• Thermoplastic insulation housing supports operation within a temperature range of -40°C to +105°C.

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Medical device circuit board assemblies

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact plating thickness and housing color specifications. Ensure compatibility with the target card edge thickness range before procurement. Confirm that the panel mount style aligns with the mechanical constraints of the final enclosure design.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count vertical interface is required for industrial or communication hardware. The 3.96 mm pitch offers robust spacing for higher voltage isolation compared to finer pitches. Consider the 5 A current rating for power distribution needs alongside signal lines in dense mounting environments.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for durability in harsh environments. The series typically includes various position counts and termination styles, serving as a foundational solution for modular electronic systems where reliable mechanical retention and electrical continuity are critical.

Edgeboard Connectors Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 84-position count, 3.96 mm pitch, and dual-edge female configuration with alternative manufacturers' catalogs.
