305-054-555-501

Edgeboard Connectors Overview

The EDAC Inc. 305-054-555-501 is a dual female card edge connector with 54 positions arranged in two rows of 27 contacts. It features a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The connector utilizes gold-plated copper alloy contacts with a 10.0µin (0.25µm) plating thickness and half-bead contact types. Insulation is provided by thermoplastic polyester, rated for operation between -40°C and +105°C. It supports panel mounting and solder termination.

Edgeboard Connectors Feature Summary

• Accepts polarizing keys for secure board alignment
• High current rating of 5A continuous
• Low profile insulator body design

Edgeboard Connectors Applications

• Industrial control systems
• Telecommunications equipment
• Computer peripheral interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and insulation material variations. Confirm that the target PCB thickness falls within the acceptable range of 0.054 to 0.070 inches for reliable engagement. Ensure compliance with RoHS3 standards if required by the end application environment.

Edgeboard Connectors Selection Notes

Select this model when a high-density 54-position interface is required with standard 0.156-inch spacing. Consider the 5A current rating and 1800VACrms dielectric strength for power or signal integrity needs. Verify compatibility with existing panel mounting hardware due to the specific flange dimensions.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options, designed for robust interconnection in demanding environments. The 305-054 variant specifically addresses applications requiring higher pin counts while maintaining standard spacing dimensions.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305-series parts for different position counts. Verify mechanical fit with alternative manufacturers' equivalents by checking row spacing and board thickness tolerances.
