305-024-521-204

Edgeboard Connectors Overview

The EDAC Inc. 305-024-521-204 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 24 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are gold-plated copper alloy, rated for 5 A current. The housing is green thermoplastic polyester, supporting vertical panel mount installation via solder pins.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for secure board retention
• Low profile insulator body construction
• Gold-plated contacts on copper alloy substrate
• Vertical panel mount configuration

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm plating thickness and material specifications. Confirm that the green insulator color matches system requirements. Ensure compatibility with 1.57 mm PCB thickness before ordering. Check lead times as manufacturing schedules may vary. Validate RoHS compliance status through the latest datasheet revision.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for 24-position signaling. The 3.96 mm pitch suits applications needing wider spacing than standard 2.54 mm connectors. Consider the vertical panel mount style for chassis integration. Verify that the 5 A current rating meets the power distribution needs of the target circuit board.

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 305-024-521-204 specifically denotes a 24-position dual-edge variant. It shares mechanical dimensions with other parts in the 305 family but differs in contact count and termination details.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers within the 305 series sharing identical 24-position dual-edge geometry and 3.96 mm pitch. Cross-referencing mechanical drawings is essential to ensure flange and housing alignment match the existing assembly design.
