305-050-521-558

Edgeboard Connectors Overview

The EDAC Inc. 305-050-521-558 is a standard card edge connector featuring 50 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm (0.140 inch) row spacing. Designed for .062 inch (1.57 mm) nominal thickness printed circuit boards, this component employs gold-plated copper alloy contacts and solder pin termination. The unit supports a continuous current rating of 5A and withstands 1800VACrms voltage.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Features a low profile insulator body construction
• Provides high dielectric strength with 1800VACrms rating

Edgeboard Connectors Applications

• High-density electronic interconnect systems
• Industrial control panel assemblies
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm exact contact plating thickness and material specifications. Ensure compatibility with the target PCB board thickness of 1.57 mm before integration. Confirm that the required polarizing key type matches the available between-contact or in-contact options documented in the official datasheet.

Edgeboard Connectors Selection Notes

Select this model when a dual-row interface with 3.96 mm pitch is required for robust signal transmission. The 5A current capacity suits applications demanding higher power handling than standard micro-connectors. Verify mechanical clearance constraints due to the vertical mounting style and panel installation requirements.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations while maintaining consistent 3.96 mm spacing. The 305 series is designed for reliable vertical panel mounting in industrial and commercial electronics environments.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers within the EDAC 305 series for alternative position counts. Verify identical 3.96 mm pitch and 1.57 mm board thickness compatibility when substituting.
