306-024-421-107

Overview

The EDAC Inc. 306-024-421-107 is a standard card edge connector classified as a receptacle within the 306 series. It features 56 positions with a 0.156 inch (3.96 mm) pitch and supports dual-edge board configurations. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin (0.25 µm) thickness, rated for 5 A current. Designed for panel mount installation at a vertical angle, it accommodates PCB thicknesses between 0.054 and 0.070 inches (1.37–1.78 mm). The housing is constructed from green thermoplastic polyester, ensuring reliable electrical performance in industrial applications.

Feature Summary

• Dual-edge female connector design for secure board insertion
• Gold-plated contacts ensure low resistance and corrosion resistance
• Panel mount configuration with vertical orientation for stable integration
• Thermoplastic polyester housing provides thermal stability and durability

Applications

• Industrial control systems requiring robust interconnects
• Communication equipment backplanes
• Automotive electronics modules
• Test and measurement instrumentation

Procurement Notes

Verify the complete part number including suffixes to confirm contact plating and mounting style. Confirm that the target application requires dual-edge compatibility and the specified 3.96 mm pitch. Ensure the PCB thickness falls within the 1.37 mm to 1.78 mm range for proper mechanical engagement. Check RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a high-density 56-position interface is required for dual-sided circuit boards. The 3.96 mm pitch offers a balance between signal density and spacing reliability. Consider the vertical panel mount style for chassis-based installations where space efficiency is critical. The gold plating is suitable for environments requiring long-term connection integrity without maintenance.

Part Context

This connector belongs to the EDAC 306 series, which includes various standard card edge connectors designed for general-purpose electronic applications. The series offers multiple position counts and mounting options to accommodate different board sizes and system architectures. Components in this line are engineered for durability and consistent electrical performance across a wide temperature range.

Replacement Considerations

Compatible substitutes include other EDAC 306 series parts with matching 56 positions and 3.96 mm pitch. Verify that alternative components support dual-edge termination and identical panel mount dimensions. Cross-reference contact material and plating specifications to maintain equivalent electrical characteristics.
