305-054-520-504

Edgeboard Connectors Overview

The EDAC Inc. 305-054-520-504 is a standard card edge connector featuring 54 positions arranged in a dual row configuration. It utilizes a 0.156-inch (3.96 mm) pitch and accepts board thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). The connector employs gold-plated copper alloy contacts with a half-beam contact type for reliable signal transmission. Designed for panel mount installation, it supports vertical orientation and solder pin termination. The housing is constructed from green thermoplastic polyester, ensuring durability within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Provides a continuous current rating of 5A with high voltage insulation capability
• Features gold-plated half-beam contacts for low insertion force and reliable connection

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring dual-edge card connections
• Industrial control systems utilizing standardized card edge modules
• Test and measurement equipment interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness, housing color variations, and mounting hardware configurations. Ensure that the selected variant matches the required polarizing key compatibility and thermal ratings for the intended application environment. Cross-reference manufacturer datasheets for precise dimensional tolerances and compliance certifications prior to final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a robust, panel-mount solution is required for dual-edge cards with a 3.96 mm pitch. The 54-position count suits applications needing moderate I/O density. Consider the 5A current rating and 105°C maximum temperature limit for environmental suitability. Verify that the vertical panel mount style aligns with the mechanical enclosure design and that solder pin termination is compatible with the assembly process.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and mounting styles to accommodate different board sizes and system architectures. The 305-054-520-504 specifically addresses needs for higher density connections in panel-mounted configurations, providing a balance of electrical performance and mechanical stability.

Edgeboard Connectors Replacement Considerations

Consult official EDAC cross-reference guides for direct substitutes. Verify that any alternative maintains the same 3.96 mm pitch, 54-position count, and dual-row configuration. Ensure mechanical compatibility regarding panel mount dimensions and solder pin specifications before substitution.
