305-068-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-068-521-502 is a standard card edge connector from the 305 series, designed for panel mount applications. It features a dual female configuration with 68 positions and a contact spacing of 0.156 inches (3.96 mm). The row spacing is 0.140 inches (3.56 mm), and it accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The contacts are made of copper alloy with gold plating, rated for 5 A current. The insulator body is constructed from thermoplastic polyester, offering an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required pin count and spacing before ordering. Confirm compatibility with the target PCB thickness of 0.062 inches. Ensure the panel mounting requirements align with the connector's physical dimensions. Check for any regional distribution restrictions or availability issues prior to finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 68-position interface is necessary. The 0.156-inch pitch suits applications where larger spacing reduces crosstalk risks. Consider the 5 A rating for power distribution needs within the specified thermal limits. Verify that the green insulator color meets visual identification standards if applicable.

Edgeboard Connectors Part Context

This model belongs to the EDAC 305 series, which specializes in standard card edge connectors. The series offers various position counts and configurations to support diverse electronic assembly requirements. The 305-068-521-502 variant specifically addresses high-density connection needs with its 68-position layout.

Edgeboard Connectors Replacement Considerations
