305-028-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-028-521-502 is a standard card edge connector designed for panel mount applications. It features a dual female configuration with 28 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm. Constructed with copper alloy contacts featuring gold plating, it ensures reliable signal transmission. The housing is made from thermoplastic polyester, providing durability within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure board insertion
• Gold-plated copper alloy contacts for corrosion resistance
• Thermoplastic polyester insulator body for structural integrity
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Automotive electronics assemblies
• Test and measurement instrumentation

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact pin count, row configuration, and termination type. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status through current manufacturer datasheets as regulatory requirements may evolve over time.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection is required for thick PCBs up to 1.57 mm. The 3.96 mm pitch offers reduced density compared to finer pitches but provides mechanical stability. Consider the vertical panel mount style for chassis integration where space constraints allow for front-accessible connections.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its ability to handle relatively thick circuit boards and its robust construction suitable for demanding environments. The 305 series typically includes various position counts and mounting styles to support diverse electronic design needs.

Edgeboard Connectors Replacement Considerations

Consult official EDAC cross-reference guides for direct substitutes. Verify that any alternative maintains identical 3.96 mm spacing and 1.57 mm board thickness acceptance to ensure mechanical fit.
