306-026-520-104

Overview

The EDAC Inc. model 306-026-520-104 is a standard card edge connector designed for dual-edge board insertion. It features 52 positions with a 0.156-inch (3.96 mm) pitch. The connector utilizes gold-plated copper alloy contacts housed in a green thermoplastic insulator. It supports a current rating of 5 A and offers an insulation resistance of 5 GOhms. The unit is configured for panel mounting at a vertical angle, accommodating a board thickness of 1.57 mm.

Feature Summary

• Dual female contact configuration for secure dual-edge card engagement
• Gold-plated copper alloy terminals ensure reliable signal transmission
• Thermoplastic housing provides structural stability and electrical isolation

Applications

• Computing and storage system interconnects
• Industrial control module connections
• Aerospace avionics board interfaces

Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and material composition. Ensure the selected variant matches the required board thickness tolerance of 1.57 mm. Confirm that the vertical panel mount style aligns with the mechanical enclosure design constraints before finalizing the purchase order.

Selection Notes

Select this component when a high-density dual-edge interface is required for rigid PCB applications. The 3.96 mm pitch allows for moderate trace spacing while maintaining robust mechanical retention. Verify compatibility with mating card edge thicknesses to prevent excessive stress on the contacts during insertion.

Part Context

This part belongs to the EDAC 306 series, which specializes in standard density card edge connectors. The series is widely utilized in OEM environments requiring reliable interconnect solutions for computing, medical, and industrial sectors. The manufacturer emphasizes rigorous quality assurance and global logistics support for these interconnect products.

Replacement Considerations

Cross-reference with other EDAC 306 series variants sharing identical pitch and position counts. Verify that alternative suppliers offer matching gold plating specifications and thermoplastic housing materials to maintain electrical and mechanical integrity.
