305-040-520-568

Edgeboard Connectors Overview

The EDAC Inc. 305-040-520-568 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 40 positions arranged in a dual-row configuration with a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts and a thermoplastic insulator body, supporting a PCB thickness of 1.57 mm. Rated for 5 A continuous current, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features low profile insulator body construction for compact integration
• Supports .062 inch nominal thickness printed circuit boards

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring vertical interconnect
• Industrial control systems utilizing polarized card edge interfaces
• High-reliability data transmission modules with specific thermal requirements

Edgeboard Connectors Procurement Notes

Verify the exact suffix code against the manufacturer's official ordering guide to ensure correct plating thickness and material specifications. Confirm that the required polarizing key type matches the connector's acceptance capabilities. Check regional availability as distribution status may vary by location. Ensure the target PCB thickness aligns with the specified 1.57 mm tolerance for optimal contact engagement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 40-position interface with 3.96 mm pitch is required for panel mounting. Consider the 5 A current rating and 105°C maximum operating temperature for environmental suitability. Verify compatibility with existing polarizing key strategies before finalizing the design. Ensure the thermoplastic housing material meets the chemical resistance needs of the application environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for robust performance in demanding environments. The series supports various position counts while maintaining consistent mechanical and electrical characteristics. These connectors are widely used in applications requiring reliable signal transmission and power delivery through card edge interfaces.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include parts with matching row count and pitch, such as 305-040-520-502 or 305-040-520-203, provided the housing color and specific termination details meet the design requirements. Always verify dimensional drawings and pinout configurations before substitution.
