305-050-521-504

Edgeboard Connectors Overview

The EDAC Inc. 305-050-521-504 is a dual-row card edge connector designed for vertical panel mount applications. It features 50 positions with a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The connector utilizes gold-plated contacts and a thermoplastic insulator body, supporting a continuous current rating of 5A and a dielectric strength of 1800VACrms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Low profile insulator body design suitable for space-constrained enclosures
• Vertical panel mount configuration with solder pin termination

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnect solutions
• Telecommunications equipment utilizing standard card edge interfaces
• Automotive electronics assemblies needing reliable signal transmission

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required polarizing key configurations and mounting hardware. Confirm that the target PCB thickness aligns with the 0.062-inch nominal specification to guarantee proper mechanical engagement and electrical contact reliability during operation.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 50 positions is required for vertical panel mounting. Ensure the application environment remains within the specified operating temperature range and that the 5A current rating meets the system's power distribution requirements without exceeding thermal limits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations, providing a modular solution for diverse electronic interconnect needs while maintaining consistent mechanical dimensions and electrical performance characteristics across the family.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC 305-050-521-501 or 305-050-521-502 if different flange diameters or insulation materials are required. Verify that substitute parts maintain the same 0.156-inch pitch and 50-position count to ensure mechanical fitment on existing panels.
