305-086-556-204

Edgeboard Connectors Overview

The EDAC Inc. 305-086-556-204 is a standard card edge connector from the 305 series, designed for dual-edge card applications. It features 86 positions with a 3.96 mm pitch and accommodates board thicknesses between 1.37 mm and 1.78 mm. The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and supports a continuous current rating of 5 A. Rated for 1800 VACrms, it offers high insulation performance. The unit employs a solder termination method and is housed in a green thermoplastic insulator, suitable for panel or PCB mounting configurations.

Edgeboard Connectors Feature Summary

• Accepts both between-contact and in-contact polarizing keys for secure alignment
• Provides robust electrical isolation with a 1800 VACrms voltage rating
• Features gold-plated contacts on a copper alloy base for durability

Edgeboard Connectors Applications

• Dual-edge card interface systems requiring polarizing key support
• High-voltage industrial control modules
• Panel-mounted electronic assemblies

Edgeboard Connectors Procurement Notes

Verify the specific insulator style code and mounting configuration requirements against official EDAC documentation before ordering. Confirm that the target printed circuit board thickness falls within the specified 1.37 mm to 1.78 mm range to ensure proper mechanical engagement. Ensure compatibility with required polarizing key types, as the connector supports both between-contact and in-contact options. Cross-reference the full part number to confirm terminal type and orientation specifications.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection with 86 positions is required for dual-edge cards. The 3.96 mm pitch allows for substantial trace spacing, reducing crosstalk risks in dense layouts. Choose this model if the application demands a 1800 VACrms rating and a 5 A current capacity. Consider the available polarizing key options to prevent misalignment during insertion. Verify that the green thermoplastic housing meets environmental and thermal requirements for the intended operating temperature range.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series, which specializes in standard card edge connectors. The series is characterized by its 3.96 mm pitch and versatile mounting options. The 305 series typically includes various position counts and termination styles to accommodate diverse board designs. This specific part represents a high-position-count variant optimized for dual-edge applications, distinguishing it from single-row or lower-count counterparts within the same family.

Edgeboard Connectors Replacement Considerations

Consult EDAC Inc. directly for verified substitute part numbers. Check for alternative models within the 305 series that match the 86-position count and 3.96 mm pitch. Ensure any replacement supports the same polarizing key compatibility and voltage ratings.
