305-084-521-578

Edgeboard Connectors Overview

The EDAC Inc. 305-084-521-578 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features an 84-position dual-row female configuration with gold-plated copper alloy contacts and solder pin termination. The component utilizes a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing, accommodating printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Low profile insulator body construction
• Dual-edge female contact interface

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring high-density interconnects
• Industrial control systems utilizing standardized card edge interfaces
• Equipment requiring polarized board insertion for alignment

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact plating thickness, material composition, and mechanical tolerances. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the panel mounting style aligns with the chassis design requirements before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, 84-position connection is required with a 3.96 mm pitch. Confirm that the application environment falls within the -40°C to +105°C operating range and that the 5 A current rating meets the electrical load demands. Verify that the vertical panel mount style fits the available space and that polarizing key support is necessary for the assembly process.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by robust copper alloy contacts, gold plating options, and versatile mounting styles including panel and board configurations. The 305 series supports various position counts and row arrangements to accommodate different density requirements in industrial and commercial electronics.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers within the EDAC 305 series for alternative position counts or row configurations. Verify that any substitute maintains the 3.96 mm spacing and 1.57 mm board thickness compatibility. Check datasheets for identical electrical ratings and mounting dimensions to ensure functional equivalence.
