305-056-556-501

Edgeboard Connectors Overview

The EDAC 305-056-556-501 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 56 positions with a contact pitch of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). It utilizes gold-plated copper alloy contacts and a thermoplastic insulator body, supporting a current rating of 5 A.

Edgeboard Connectors Feature Summary

• Dual-row configuration with card extender functionality
• Vertical straddle mount installation style
• Gold-plated contacts on copper alloy substrate

Edgeboard Connectors Applications

• Panel-mounted electronic interconnects
• Card edge board termination systems
• Industrial control module interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, plating specifications, and mounting variations. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the dual-row layout matches the system design requirements before procurement.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for 56-position card edge applications. The 3.96 mm pitch and 1.57 mm board thickness acceptance are critical constraints. Confirm that the straddle mount style aligns with the mechanical enclosure design and that the 5 A current rating meets the electrical load requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its robust construction for panel mounting and compatibility with nominal 0.062-inch thick PCBs. The 305 series offers various position counts while maintaining consistent pitch and mounting characteristics across the family.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants having identical 56-position counts and 3.96 mm pitch. Verify mechanical fit and electrical ratings match exactly. No direct substitute part numbers are confirmed in public documentation.
