305-078-500-212

Edgeboard Connectors Overview

The EDAC Inc. 305-078-500-212 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 78 positions with a 3.96 mm (0.156 inch) pitch and a 3.56 mm row spacing. The connector supports a 1.57 mm PCB thickness and provides a 5 A current rating with 1800 VACrms dielectric strength. Contacts are gold-plated copper alloy, housed in green thermoplastic polyester. It utilizes solder lug termination and panel mount vertical installation.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Dual-row configuration for high-density signal routing
• Gold-plated contacts ensure reliable conductivity and corrosion resistance

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation boards

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm exact plating thickness, housing color, and mounting hardware compatibility. Ensure that the target PCB design accommodates the specified 1.57 mm thickness and 3.96 mm pitch dimensions before procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. The 78-position count suits applications needing extensive I/O or data lines. Verify that the system environment remains within the -40 C to +105 C operating temperature range for optimal performance.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, all sharing the consistent 3.96 mm pitch architecture. The 305 series is widely used in industrial and commercial electronics for reliable board-to-board or board-to-backplane connections.

Edgeboard Connectors Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other EDAC 305 series variants only if they match the 78-position, 3.96 mm pitch, and dual-row specifications exactly.
