305-084-555-208

Edgeboard Connectors Overview

The EDAC 305-084-555-208 is a standard card edge connector from the 305 series, designed for panel-mounted vertical installation. It features an 84-position dual-row configuration with a 3.96 mm (0.156 inch) contact spacing and 3.56 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Constructed with copper alloy contacts featuring gold plating, it supports a continuous current rating of 5 A. The housing utilizes thermoplastic material, providing an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Low profile insulator body design suitable for space-constrained panel applications
• Gold-plated copper alloy contacts ensure reliable electrical connectivity

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems
• Industrial control module connections
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, termination style, and insulation color. Ensure compatibility with the target PCB thickness of 1.57 mm and required polarizing key configurations before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density 84-position connection is required for double-sided card edge boards. The 3.96 mm pitch accommodates larger signal traces compared to finer pitches. Verify that the application environment remains within the specified -40°C to +105°C thermal limits and requires panel-mount vertical orientation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its robust construction for industrial environments and compatibility with polarizing keys. Similar parts in the series vary primarily by position count and termination method while maintaining consistent mechanical dimensions and electrical ratings.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 84-position dual-row layout, 3.96 mm pitch, and panel-mount vertical form factor. Cross-reference the 305 series ordering guide for alternative part numbers with identical mechanical specifications but different termination styles or colors.
