305-056-520-504

Edgeboard Connectors Overview

The EDAC Inc. 305-056-520-504 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 56 positions with a 0.156-inch (3.96 mm) pitch and accepts PCB thicknesses between 0.054 and 0.070 inches. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin plating thickness and offers a 5 A current rating. It employs a solder pin termination style and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified card types
• Gold-plated copper alloy contacts for reliable conductivity
• Solder pin termination for secure panel mounting
• Thermoplastic polyester insulation housing

Edgeboard Connectors Applications

• Panel-mounted electronic interconnects

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to ensure correct contact plating and housing material specifications. Confirm that the required PCB thickness falls within the 0.054 to 0.070 inch acceptance range. Check for RoHS compliance status if environmental regulations apply to your assembly process.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution for dual-edge cards is required. Ensure the design accommodates the 3.96 mm pitch and 56-position layout. Verify that the application environment stays within the specified -40°C to +105°C operating temperature limits for optimal performance.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and mounting options for industrial and commercial electronics. The 305-056 variant specifically addresses needs for higher density connections in a dual-edge format.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for direct substitutes with different position counts or flange configurations. Cross-reference compatible parts from other manufacturers only if mechanical dimensions and electrical ratings match exactly.
