306-028-521-104

Overview

The EDAC Inc. 306-028-521-104 is a dual-edge female card edge connector from the 306 series, designed for panel mount applications. It features 56 positions with a 0.156-inch (3.96mm) contact spacing and accepts non-specified dual-edge cards. The contacts are made of copper alloy with a gold finish, ensuring reliable signal transmission. The insulator is constructed from thermoplastic polyester, providing durability in demanding environments. This component supports a wide operating temperature range and complies with RoHS3 standards.

Feature Summary

• Dual-edge female configuration for secure board insertion
• Gold-plated copper alloy contacts for corrosion resistance
• Thermoplastic polyester insulator body for structural integrity

Applications

• Industrial control systems requiring robust interconnects
• Communication equipment backplanes
• Medical device circuit boards

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required flange characteristics and insulation color. Confirm that the selected variant matches the intended PCB thickness and mounting style. Cross-reference the manufacturer's latest datasheet for any updates on material specifications or compliance certifications before finalizing procurement orders.

Selection Notes

Select this connector when a 0.156-inch pitch is required for high-reliability applications. Ensure the host PCB design accommodates the specified dual-edge card thickness range. Consider the green insulator color for visual identification if required by assembly processes. Verify that the panel mount installation type aligns with the mechanical constraints of the enclosure design.

Part Context

This component belongs to the EDAC 306 series, which offers various configurations for card edge connections. The series is known for its versatility in industrial and commercial applications. The 306-028-521-104 specifically provides a 56-position interface, balancing density and accessibility for complex circuit designs.

Replacement Considerations

Direct substitutes within the same series include part numbers with identical pin counts and spacing, such as 306-028-520-104, differing primarily in flange or color attributes. Always verify mechanical dimensions and electrical ratings before substituting.
