305-028-521-207

Edgeboard Connectors Overview

The EDAC Inc. 305-028-521-207 is a standard card edge connector from the 305 series, designed for panel mounting with a vertical orientation. It features 28 positions with a contact spacing of 3.96 mm (0.156 inches) and accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The connector utilizes gold-plated copper alloy contacts and employs a solder pin termination method. Rated for 5 A continuous current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Low profile insulator body constructed from thermoplastic material
• Provides high insulation resistance of 5 GOhms

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring robust card edge interfaces
• Industrial control systems utilizing standardized board thicknesses
• Equipment needing polarized connection alignment for dual-row headers

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and termination style variations. Ensure compatibility with existing panel cutouts and PCB stack-up requirements before procurement. Cross-reference the manufacturer's latest ordering guide to confirm current production status and availability constraints.

Edgeboard Connectors Selection Notes

Select this component when a 28-position dual-row interface is required for panels. Confirm that the target PCB thickness aligns with the 1.57 mm specification. Verify that the application environment falls within the specified operating temperature range and that the 5 A current rating meets the electrical load requirements of the system design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options while maintaining consistent spacing and mechanical profiles. These connectors are engineered for reliable performance in demanding environments, supporting both through-hole and panel-mount configurations with durable materials.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other 28-position variants within the EDAC 305 series, such as 305-028-520-207 or 305-028-521-501, provided the termination style and housing color match the design requirements. Verify mechanical dimensions and electrical ratings before substitution.
