305-054-500-558

Edgeboard Connectors Overview

The EDAC Inc. 305-054-500-558 is a standard card edge connector header featuring 54 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and is designed for vertical panel mounting with solder pin termination. The connector supports printed circuit boards with a nominal thickness of 1.57 mm. Constructed with copper alloy contacts that are gold-plated, it provides a continuous current rating of 5 A. The insulating body is made of thermoplastic material.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Features a low profile insulator body design
• Utilizes gold-plated copper alloy contacts for reliable conductivity

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized board thicknesses
• Test and measurement instrumentation panels

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required polarizing key configurations and terminal styles. Confirm that the target application accommodates the specified 1.57 mm PCB thickness and 3.96 mm pitch constraints. Cross-reference the manufacturer datasheet for detailed mechanical dimensions and mating force requirements before integration into the final assembly design.

Edgeboard Connectors Selection Notes

Select this component when a dual-row header with 54 positions is required for vertical panel installation. Ensure the design environment operates within the specified temperature range and voltage ratings. Consider the availability of compatible polarizing keys if positional security is critical for the specific application scenario.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which is engineered for high-reliability interconnect solutions. The series is characterized by its ability to accept polarizing keys and support various board thicknesses. It serves as a standard interface for connecting edge-card modules to backplanes or chassis-mounted headers in demanding electronic environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical position counts and pitch but different mounting or termination variations, such as the 305-054-556-278. Verify mechanical fit and electrical ratings before swapping components.
