305-066-521-208

Edgeboard Connectors Overview

The EDAC Inc. 305-066-521-208 is a standard card edge connector from the 305 series, designed for dual female termination on non-specified double-sided cards. It features 66 positions with a 0.156-inch (3.96 mm) pitch and accepts board thicknesses between 0.054 and 0.070 inches (1.37 to 1.78 mm). The contacts are made of copper alloy with gold plating, rated for 5 A continuous current. Insulation is provided by thermoplastic polyester, supporting an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for reliable connection to double-sided card edges
• Gold-plated copper alloy contacts ensure stable signal transmission and corrosion resistance
• Thermoplastic polyester housing provides structural integrity within specified thermal limits
• Accepts polarizing keys for precise alignment during panel mount installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust vertical interconnects
• Communication equipment utilizing standardized card edge interfaces
• Medical devices needing high-reliability panel-mounted connections
• Energy sector hardware with specific thermal and current requirements

Edgeboard Connectors Procurement Notes

Verify the exact pin count and pitch against the official datasheet before ordering. Confirm that the target PCB thickness falls within the 1.37 mm to 1.78 mm acceptance range. Ensure compatibility with the required polarizing key type if alignment is critical. Check RoHS compliance status directly from the manufacturer's documentation for regulatory adherence.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 66-position interface is required for double-sided boards. The 3.96 mm pitch dictates the trace spacing on the mating card. Verify that the 5 A current rating meets the circuit demands. Consider the vertical panel mount style for integration into chassis designs where space efficiency is prioritized over surface mounting.
