305-074-520-504

Edgeboard Connectors Overview

The EDAC Inc. 305-074-520-504 is a standard card edge connector from the 305 series, designed for vertical panel mounting applications. It features a dual female configuration with 74 positions and a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts with a half-beam termination type, secured via solder pins. It accommodates printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and offers a continuous current rating of 5 A. The insulator body is constructed from thermoplastic polyester, providing a low-profile design suitable for dense electronic assemblies.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body to minimize overall assembly height
• Utilizes half-beam contact type for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standard card edge interfaces
• Automotive electronics modules needing high-reliability connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pin count, plating thickness, and flange specifications. Confirm that the required polarizing key compatibility matches the intended PCB design. Cross-reference the RoHS status and material composition with current regulatory requirements for the target market before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel mount solution with 74 positions is required. Ensure the host PCB thickness aligns with the 0.062-inch nominal specification. Consider the 5 A current rating and 1800 VACrms insulation voltage for electrical safety margins. Verify that the 0.156-inch pitch fits within the available board space constraints compared to alternative series options.

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 provides various position counts and mounting styles to support diverse interface needs. The 305-074 variant specifically addresses applications requiring a higher density connection point while maintaining the structural integrity associated with the 305 family design.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or flange configurations. Verify mechanical footprint compatibility before substituting with other manufacturers' products, as pitch and board thickness tolerances may vary significantly across different brands.
