305-070-500-207

Edgeboard Connectors Overview

The EDAC Inc. 305-070-500-207 is a standard card edge connector featuring 70 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) contact pitch and accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component employs gold plating on the mating area and tin plating with nickel underplating on the tails. Rated for 5 amps, it offers a maximum contact resistance of 10 milliohms and an insulation resistance of 5 GOhms. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration supporting 70 positions with 3.96 mm spacing
• Gold-plated contacts ensure reliable signal transmission
• Compatible with 1.57 mm thick PCBs for panel mounting

Edgeboard Connectors Applications

• Industrial control systems requiring high-density connections
• Telecommunications equipment interfaces
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm plating specifications and termination types. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the 5-amp current rating aligns with the application's electrical requirements. Cross-reference the operating temperature range with environmental conditions.

Edgeboard Connectors Selection Notes

Select this model when a dual-row card edge connector with a 3.96 mm pitch is required. The 70-position count suits applications needing substantial I/O density within a vertical panel mount form factor. Verify that the thermoplastic insulator body meets thermal stability needs up to 105°C. Ensure the solder lug or pin termination matches the assembly process.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its robust construction and compatibility with various board thicknesses. The 305 series supports both single and double-sided card edges, providing flexibility for different circuit board designs while maintaining consistent electrical performance standards.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching position counts and pitch dimensions. Verify equivalent electrical ratings and mechanical fit before substitution.
