305-070-500-201

Edgeboard Connectors Overview

The EDAC Inc. 305-070-500-201 is a standard card edge connector from the 305 series, designed for reliable signal transmission in electronic assemblies. It features 70 positions with a 3.96 mm pitch and supports dual-edge card insertion. The connector utilizes gold-plated copper alloy contacts to ensure low contact resistance and durability. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic material, providing insulation and mechanical stability.

Edgeboard Connectors Feature Summary

• Dual-edge design accommodates double-sided circuit board fingers for increased I/O density.
• Gold-plated contacts provide corrosion resistance and stable electrical performance over repeated mating cycles.
• Thermoplastic housing offers robust insulation and structural integrity for panel or PCB mounting applications.

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment utilizing modular card architectures
• Test and measurement instruments needing reliable signal paths

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness, housing color, and termination style. Ensure compatibility with the target card edge thickness of 1.57 mm. Confirm that the 70-position configuration matches the required circuit layout. Cross-reference the RoHS compliance status with the latest manufacturer datasheet before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a 70-position interface with a 3.96 mm pitch is required. The dual-edge configuration is suitable for applications demanding higher pin counts in a single connector footprint. Verify that the operating environment falls within the specified -40°C to +105°C range. Ensure the mating card meets the dimensional tolerances for the 1.57 mm thickness specification.

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 to support diverse electronic design needs. The 305-070-500-201 specifically addresses requirements for medium-to-high density connections with standardized spacing. It serves as a critical interface component between backplanes and plug-in modules.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 70-position count, 3.96 mm pitch, and dual-edge form factor. Verify that alternative components maintain identical current ratings and temperature specifications. Check for compatible termination types and housing materials to ensure mechanical fit.
