305-070-521-512

Edgeboard Connectors Overview

The EDAC Inc. 305-070-521-512 is a standard card edge connector featuring 70 positions with a 3.96 mm pitch. It utilizes dual-row female contacts made of copper alloy with gold plating, rated for 5 A continuous current and 1800 VACrms insulation. Designed for panel mount installation via solder pin termination, the unit accommodates a board thickness of 1.57 mm. The housing is constructed from thermoplastic polyester, ensuring durability in demanding environments.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Dual-row configuration provides high-density connectivity options
• Gold-plated copper alloy contacts ensure reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment infrastructure
• Medical device hardware assemblies

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or official manufacturer channels. Confirm that the specific part number matches project requirements regarding contact count and termination style. Ensure compliance with RoHS directives if applicable to the assembly. Review datasheet specifications for thermal and electrical limits before integration into final designs.

Edgeboard Connectors Selection Notes

Select this model when a 70-position interface with a 3.96 mm pitch is required. The dual-row layout supports higher density compared to single-row alternatives. Verify compatibility with the target PCB thickness of 1.57 mm. Consider the 5 A current rating and 1800 VACrms insulation voltage for circuit safety margins. Panel mount orientation suits fixed installations rather than flexible cabling.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series, which specializes in standard card edge connectors. The series offers various position counts while maintaining consistent 3.96 mm spacing. These connectors are engineered for reliability in industrial and commercial applications, providing stable mechanical and electrical connections for printed circuit boards.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models with identical pitch but different position counts, such as 305-040-520-268 or 305-048-520-512. Cross-series replacements require careful verification of mechanical dimensions and electrical ratings to ensure functional equivalence.
