305-078-520-212

Edgeboard Connectors Overview

The EDAC Inc. 305-078-520-212 is a standard card edge connector from the 305 Series, designed for dual-edge board applications. It features 78 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum current rating of 5 A. The connector utilizes gold-plated copper alloy contacts housed in green thermoplastic polyester. It is configured as a female header with solder pin termination and panel mount installation.

Edgeboard Connectors Feature Summary

• Dual-edge design accommodates boards with conductive edges on both sides
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance
• Thermoplastic polyester housing provides structural stability and insulation

Edgeboard Connectors Applications

• High-density electronic interconnects
• Industrial control systems
• Telecommunications equipment

Edgeboard Connectors Procurement Notes

Verify the specific position count and contact configuration against the official datasheet before procurement. Confirm that the target PCB thickness aligns with the connector's mechanical specifications to ensure proper mating. Check regional availability status through authorized distributors, as supply constraints may affect immediate fulfillment.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge interface is required with a 3.96 mm pitch. Ensure the application environment remains within the specified operating temperature range. Verify that the 5 A current rating meets the circuit requirements and that the panel mount style fits the enclosure design constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers a range of standard card edge connectors. The series provides various position counts and housing colors to suit different assembly needs. The 305-078-520-212 specifically addresses high-pin-count applications requiring robust dual-edge connectivity.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 78-position count, 3.96 mm pitch, and dual-edge configuration. Verify compatibility with existing PCB layouts and mounting hardware. Cross-reference with other EDAC 305 Series variants if exact matches are unavailable.
