306-028-520-112

Overview

The EDAC Inc. 306-028-520-112 is a standard card edge connector from the 306 Series, designed for panel mounting applications. It features a dual female configuration with 56 positions and a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. It supports a current rating of 5 A and operates within a temperature range of -40°C to 105°C. The housing is constructed from green thermoplastic polyester, providing durability and insulation.

Feature Summary

• Dual-edge female design accommodates non-specified double-sided circuit boards
• Gold-plated copper alloy contacts provide corrosion resistance and conductivity
• Panel mount installation style ensures secure mechanical positioning
• Thermoplastic polyester insulator offers thermal stability and electrical isolation

Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment board connections
• Medical device internal circuitry interfaces
• Energy sector instrumentation panels

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with the target PCB thickness range of 0.054 to 0.070 inches. Confirm RoHS compliance status and lead time requirements directly with authorized distributors prior to purchase.

Selection Notes

Select this component when a high-density 56-position interface is required for panel-mounted assemblies. The 3.96 mm pitch allows for substantial trace clearance on double-sided boards. Consider the 5 A current rating for power distribution needs and verify that the vertical mounting angle fits the enclosure constraints.

Part Context

This part belongs to the EDAC 306 Series, a line of standard card edge connectors known for their versatility in industrial and commercial applications. The series offers various position counts and mounting styles, with the 306-028 variant specifically addressing high-pin-count requirements through its dual-row configuration.

Replacement Considerations

Consult the EDAC 306 Series Ordering Guide for direct substitutes with different position counts or contact materials. Verify dimensional compatibility with existing panel cutouts and PCB stack-ups before transitioning to alternative part numbers.
