305-064-520-502

Edgeboard Connectors Overview

The EDAC Inc. 305-064-520-502 is a standard card edge connector designed for dual-edge board applications. It features 64 positions arranged in two rows with a 0.156-inch (3.96mm) pitch. The connector utilizes female contacts made of copper alloy with gold plating, ensuring reliable signal transmission. It supports printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches. The unit employs a solder pin termination method and is housed in green thermoplastic insulation. Operating temperatures range from -40°C to +105°C, and it complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure board insertion
• Gold-plated copper alloy terminals for enhanced conductivity
• Thermoplastic housing providing thermal stability up to 105°C
• Solder pin termination for robust PCB mounting

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Automotive electronic modules
• Test and measurement instrumentation

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC 305 Series Ordering Guide to ensure correct pitch, contact type, and flange characteristics. Confirm that the target application board thickness falls within the specified 0.054 to 0.070 inch range to guarantee proper mechanical engagement. Check for RoHS3 compliance requirements if operating in regulated regions. Ensure soldering processes align with the thermal ratings of the thermoplastic insulation material.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection with a 3.96mm pitch is required for 64-position interfaces. Consider the 0.156-inch spacing relative to available board real estate and neighboring components. Evaluate the need for gold plating thickness based on expected mating cycles and environmental exposure. Compare against similar series parts if different flange styles or panel mount configurations are necessary for the specific chassis design constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors, which offers various position counts and pitch options. The series is characterized by its versatility in industrial and commercial applications. The 305-064 variant specifically addresses higher density needs compared to lower-position counterparts like the 305-040 models, while maintaining the same structural reliability and material specifications typical of the line.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include other 305-series connectors with matching 64-position dual-edge specifications. Verify compatibility with existing tooling and board layouts before switching between variants with different flange diameters or termination styles.
