305-038-556-504

Edgeboard Connectors Overview

The EDAC 305-038-556-504 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 38 positions with a 3.96 mm pitch and supports a nominal printed circuit board thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts rated for 5 A continuous current. Constructed with a thermoplastic insulator, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Provides a 5A continuous current rating with 1800VACrms dielectric strength
• Features low profile insulator body construction

Edgeboard Connectors Applications

• Vertical panel mount interconnects
• Dual edge card edge applications
• Industrial control systems requiring polarizing key support

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct contact plating and material specifications. Confirm that the required polarizing key type matches the connector's acceptance capabilities. Check regional availability as distribution may be limited or restricted in certain areas.

Edgeboard Connectors Selection Notes

Select this component when a 38-position dual row interface is required with a 3.96 mm spacing. Ensure the host PCB thickness aligns with the 1.57 mm nominal specification. Consider the vertical panel mount style and the need for polarizing key compatibility during system design integration.

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 accept polarizing keys and its robust electrical ratings. Variants within the series differ primarily in position count and specific housing configurations while maintaining consistent pitch and mounting characteristics.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305 series variants such as 305-028-556-504 or 305-038-520-502 if position counts or contact plating variations are needed. Verify mechanical fit and electrical ratings before substituting.
