305-070-521-212

Edgeboard Connectors Overview

The EDAC Inc. 305-070-521-212 is a standard card edge connector designed for panel mount applications. It features a dual female configuration with 70 positions arranged in two rows of 35. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are made of copper alloy with a gold finish, ensuring reliable conductivity. Termination is achieved via solder pins, and the insulator body is constructed from thermoplastic polyester.

Edgeboard Connectors Feature Summary

• Dual-edge female design accommodating double-sided PCBs
• Gold-plated copper alloy contacts for corrosion resistance
• Vertical panel mount orientation for secure installation
• Compatible with 0.062 inch nominal thickness circuit boards

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation panels
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and insulator color variants. Ensure compatibility with the target PCB thickness of 0.062 inches before procurement. Confirm that the panel mount style aligns with the mechanical enclosure requirements. Cross-reference the 70-position count against the design specifications to prevent mismatched assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge interface with 3.96 mm pitch is required for vertical panel mounting. The gold-plated contacts are suitable for environments demanding high reliability and low contact resistance. Consider the 0.062 inch board thickness constraint during mechanical design. This series offers a standardized solution for industrial applications needing durable card edge connectivity.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors, which are characterized by their use of 0.156 inch (3.96 mm) spacing. The series provides various position counts and termination styles to support diverse electronic assembly needs. The 305 series is widely recognized in industrial and commercial sectors for its consistent performance and standardized dimensions.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical spacing and position counts but different suffixes for minor variations. Verify that any replacement maintains the 3.96 mm pitch and 0.062 inch board thickness compatibility. Check if alternative suffixes offer different contact finishes or insulator colors without altering the functional footprint.
