305-084-556-501

Edgeboard Connectors Overview

The EDAC Inc. 305-084-556-501 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 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and solder pin termination for secure board attachment. It supports a PCB thickness of 1.57 mm and provides a continuous current rating of 5 A. The housing is constructed from green thermoplastic material, ensuring reliable insulation and mechanical stability within electronic assemblies.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for enhanced alignment and security
• Provides high dielectric strength with a 1800VACrms insulation capability
• Features gold-plated contacts to ensure low resistance and corrosion resistance
• Designed for robust panel mounting with vertical installation geometry

Edgeboard Connectors Applications

• High-density backplane interconnections
• Industrial control system modules
• Telecommunications equipment interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm contact plating thickness, housing color, and termination style. Ensure compatibility with the target PCB stack-up and mating card edge thickness. Confirm that the polarizing key requirements match the system design specifications before procurement.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count dual-row interface is required with a 3.96 mm pitch. Consider the 5 A current rating and 1800VACrms insulation for demanding electrical environments. Verify that the panel mount form factor aligns with the chassis design constraints and that the vertical orientation fits the available spatial envelope.
