305-070-520-208

Edgeboard Connectors Overview

The EDAC Inc. 305-070-520-208 is a standard card edge connector header featuring 70 positions with a 3.96 mm pitch. It utilizes gold-plated copper alloy contacts and solder pin termination for secure electrical connections. Designed for panel mounting at a vertical angle, this dual-row component accommodates printed circuit boards with a nominal thickness of 1.57 mm. The unit provides a continuous current rating of 5 A and supports an operating temperature range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for enhanced alignment
• Features a low-profile insulator body constructed from thermoplastic polyester
• Provides reliable connection through gold-plated copper alloy contacts

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connectivity
• Telecommunications equipment utilizing standardized card edge interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm contact plating, termination style, and insulation material. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the panel mount orientation aligns with the mechanical design constraints of the enclosure.

Edgeboard Connectors Selection Notes

Select this component when a 70-position vertical header is required for dual-edge card applications. Confirm that the 3.96 mm pitch matches the mating card layout and that the 5 A current rating satisfies the system's power distribution requirements without exceeding thermal limits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options while maintaining consistent mechanical dimensions and electrical ratings across the family, facilitating modular design approaches in electronic hardware development.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series headers such as 305-070-520-204 or 305-070-556-568 to identify alternatives with different termination styles or mounting configurations while preserving the same position count and pitch specifications.
