305-084-555-203

Edgeboard Connectors Overview

The EDAC Inc. 305-084-555-203 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-row configuration with a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and utilizes gold-plated copper alloy contacts. Rated for 5 A continuous current, it employs a solder pin termination type.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low profile insulator body constructed from thermoplastic material
• Provides reliable electrical connection through gold-plated copper alloy contacts

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment utilizing standardized card edge interfaces
• Test and measurement devices needing robust panel-mounted connectors

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required polarizing key configurations and terminal types. Confirm that the selected variant matches the necessary current rating and voltage specifications for the target application environment. Cross-reference the datasheet for precise mechanical dimensions to validate panel cutout requirements before procurement.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count, dual-row interface is required for vertical panel mounting. Ensure the design accommodates the specified 0.156-inch pitch and supports the 5 A current capacity. Consider the availability of compatible polarizing keys if board retention and alignment are critical operational requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for their versatility in industrial and commercial electronics. The series offers various position counts and termination styles, providing engineers with scalable solutions for connecting double-sided PCBs to system backplanes or chassis panels.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts like 305-058-555-203 or 305-052-555-203, which share identical pitch and row spacing but differ in position count. Verify that any alternative maintains the 0.062-inch board thickness tolerance and dual-row configuration.
