306-026-521-101

Overview

The EDAC Inc. model 306-026-521-101 is a dual-edge card edge connector designed for vertical board-to-board applications. It features 52 positions with a contact spacing of 0.156 inches (3.96mm). The connector utilizes female contacts with gold plating to ensure reliable signal transmission. The insulator body is green, and the unit is constructed for through-hole mounting on printed circuit boards.

Feature Summary

• Dual-edge female configuration for secure board insertion
• Gold-plated contacts for enhanced conductivity and corrosion resistance
• Vertical orientation suitable for standard PCB assembly processes

Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Consumer electronics internal module connections

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pin count and plating specifications. Ensure compatibility with the target PCB thickness and hole dimensions before finalizing procurement orders to prevent assembly mismatches.

Selection Notes

Select this component when a high-density dual-edge interface is required with a 0.156-inch pitch. Consider the vertical mounting style and through-hole termination method for integration into existing PCB layouts that support this form factor.

Part Context

This part belongs to the EDAC 306 series of edgeboard connectors. The series offers various position counts and contact configurations, providing standardized solutions for connecting daughterboards to motherboards in compact electronic assemblies.

Replacement Considerations

Direct substitutes must match the 52-position count, 0.156-inch spacing, and dual-edge female design. Verify mechanical dimensions and electrical ratings against alternative manufacturers' equivalent parts.
