305-066-556-503

Edgeboard Connectors Overview

The EDAC Inc. 305-066-556-503 is a dual female card edge connector designed for board edge and straddle mount applications. It features 66 positions with a 0.156-inch (3.96mm) spacing across two rows. The contacts are made of copper alloy with a gold finish, utilizing a semi-crimping termination method via solder. The housing is constructed from green thermoplastic polyester, supporting PCB thicknesses between 0.054 and 0.070 inches. It operates within a temperature range of -40°C to 105°C and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Straddle mount installation for secure board edge connection
• Gold-plated copper alloy contacts for reliable conductivity
• Thermoplastic polyester insulation for thermal stability

Edgeboard Connectors Applications

• Card extender modules
• Adapter boards requiring board edge connectivity
• Industrial control systems using standard card edge interfaces

Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to ensure compatibility with target PCB stack-up and mounting requirements. Confirm that the 66-position count and 0.156-inch pitch align with the design specifications. Check for any series-specific ordering guides regarding flange characteristics or termination details before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 66-position interface is required for straddle mounting on board edges. Ensure the mating card thickness falls within the 0.054 to 0.070-inch range. Consider the operating temperature limits and RoHS3 compliance if environmental regulations apply. Verify that the semi-crimping solder termination method matches the assembly process capabilities.
