305-084-520-203

Edgeboard Connectors Overview

The EDAC Inc. 305-084-520-203 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 84 positions arranged in two rows with a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Electrical specifications include a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are constructed from copper alloy with gold plating, housed in a thermoplastic body.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low profile insulator body for compact installation
• Utilizes half-beehive contact type for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing dual-edge card configurations
• Test and measurement instruments needing high-density vertical connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required polarizing key types and flange characteristics. Confirm that the target application supports the specified 1.57 mm board thickness range. Check RoHS compliance status against current regulatory requirements for the destination market. Ensure the selected variant matches the necessary voltage ratings for the intended operational environment.

Edgeboard Connectors Selection Notes

Select this component when a high-position-count vertical connector is required for dual-edge cards. Consider the 3.96 mm pitch for spacing constraints within the enclosure design. Evaluate the need for polarizing keys if mechanical stability during insertion is critical. Compare against other series members if different board thicknesses or row spacings are needed.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and mounting styles to accommodate diverse design requirements. The 305-084-520-203 specifically addresses applications needing a high density of connections in a vertical panel-mount configuration.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series variants with similar pin counts and pitch. Verify mechanical dimensions and electrical ratings before cross-referencing with competitors. Ensure any replacement maintains the same panel mount style and vertical orientation.
