305-066-521-507

Edgeboard Connectors Overview

The EDAC Inc. 305-066-521-507 is a standard card edge connector from the 305 series, designed for panel mount vertical installation. It features 66 positions with a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Contacts are made of copper alloy with gold plating, rated for 5 A continuous current and 1800 VACrms insulation voltage. The insulator body is green thermoplastic, operating between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from high-temperature thermoplastic
• Provides dual female contact configuration with solder pin termination

Edgeboard Connectors Applications

• High-performance microcontroller interface connections
• Embedded system board-to-panel interconnects
• Industrial control unit signal routing

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure correct contact termination and mounting style compatibility. Confirm that the target PCB thickness falls within the specified acceptance range of 1.37 mm to 1.78 mm before finalizing procurement orders to prevent mechanical fit issues.

Edgeboard Connectors Selection Notes

Select this component when a 66-position dual-row connection is required for thick PCBs up to 1.57 mm. Ensure the application environment supports the specified temperature range and that the mating card edge design accommodates the 3.96 mm pitch. Verify that the panel cutout dimensions align with the connector's flange specifications for proper mechanical retention.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors, which are engineered for robust industrial and commercial applications. The series offers various position counts and mounting options, utilizing gold-plated copper alloy contacts for reliable conductivity. The 305 series is characterized by its ability to handle higher currents and voltages compared to standard lightweight connectors.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with different position counts or termination styles. Cross-reference compatible parts from other manufacturers only if they match the 3.96 mm pitch, 1.57 mm board thickness, and dual-row vertical panel mount configuration.
