305-054-556-258

Edgeboard Connectors Overview

The EDAC Inc. 305-054-556-258 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 with a row pitch of 3.56 mm (0.140 inch). Designed for .156 inch thick printed circuit boards, this vertical panel-mount unit employs gold-plated copper alloy contacts and solder pin termination. The component supports a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage.

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 robust card edge interfaces
• Telecommunications equipment utilizing standardized module connections
• Test and measurement instrumentation with high-density signal routing

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and insulation color specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the vertical panel mount style aligns with the mechanical enclosure design requirements for proper installation.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface with 3.96 mm spacing is required for heavy-duty applications. The 5 A current rating makes it suitable for power distribution within modular systems. Verify that the vertical orientation and panel mount style fit the assembly constraints compared to surface mount alternatives.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations while maintaining consistent 3.96 mm spacing. The 305 series is designed for industrial environments requiring durable connections between backplanes and plug-in modules.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series headers with identical 54-position dual-row layouts and 3.96 mm pitch. Verify that alternative part numbers maintain the same 1.57 mm board thickness tolerance and vertical mounting angle to ensure mechanical interchangeability.
