305-044-520-501

Edgeboard Connectors Overview

The EDAC Inc. 305-044-520-501 is a standard card edge connector from the 305 series, designed for panel mount applications. It features a dual female configuration with 44 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and accepts board thicknesses ranging from 1.37 mm to 1.78 mm. Contacts are made of copper alloy with gold plating, providing a continuous current rating of 5 A. The termination method is solder pin, ensuring secure through-hole installation.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for non-specified dual-edge card acceptance
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Panel mount vertical orientation with solder pin termination
• Accepts between-contact and in-contact polarizing keys

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized connector pitches
• Test and measurement instrumentation boards
• Automotive electronic modules needing high-current connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering.

Edgeboard Connectors Selection Notes

Select this component when a 44-position dual-row interface is required with a 3.96 mm pitch. It is suitable for applications demanding a 5 A current rating and panel-mount stability. Consider the vertical orientation and solder pin termination for assembly constraints. Verify that the host board supports dual-edge card insertion and compatible polarizing key requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-044 variant specifically provides a 44-position layout. It is distinct from single-row or different pitch alternatives within the broader EDAC portfolio.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 44-position dual female configurations and 3.96 mm pitch. Cross-brand replacements require matching pitch, row count, current rating, and mounting style. Verify mechanical dimensions and electrical ratings before substitution.
