305-028-500-578

Edgeboard Connectors Overview

The EDAC Inc. 305-028-500-578 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 28 positions in a dual configuration with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts and a solder lug termination type. It accommodates printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and provides a continuous current rating of 5 A.

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 panel-mounted interconnects
• Test and measurement equipment utilizing standardized card edge interfaces
• Embedded computing modules needing high-reliability signal transmission

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and housing color variations. Ensure that the selected variant matches the required polarizing key compatibility and thermal ratings for the intended operational environment before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm pitch is required for panel mounting. Confirm that the target PCB thickness aligns with the 1.57 mm specification and that the 5 A current rating meets the system's power distribution requirements without exceeding thermal limits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for general-purpose electronic interconnections. The series offers various position counts and termination styles, maintaining consistent mechanical dimensions and electrical characteristics across different configurations within the product line.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants with matching 28-position dual configurations. Verify that alternative parts maintain identical 3.96 mm spacing, 1.57 mm board thickness acceptance, and panel mount vertical installation requirements to ensure mechanical interchangeability.
