305-052-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-052-521-258 is a dual female card edge connector featuring 52 positions arranged in two rows of 26 contacts each. It utilizes a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The component offers a continuous current rating of 5A and withstands 1800VACrms dielectric voltage. Contacts are gold-plated copper alloy, ensuring reliable signal transmission within an operating temperature range of -40°C to 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 thermoplastic polyester
• Provides robust electrical performance with high dielectric voltage resistance

Edgeboard Connectors Applications

• Industrial control systems requiring secure card edge interfacing
• Telecommunications equipment utilizing standardized board dimensions
• Automotive electronics modules needing high reliability connectors

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to ensure correct flange features and mounting style. Confirm that the target application supports the specified 5A current rating and 1800VACrms insulation requirements. Check manufacturer lead times as components may be produced to order. Ensure compliance with RoHS3 standards if required by project specifications.

Edgeboard Connectors Selection Notes

Select this connector when a dual-sided female interface is required for 0.062-inch thick PCBs. The 3.96mm pitch suits applications prioritizing mechanical stability over high-density routing. Verify compatibility with existing polarizing key systems before integration. Consider thermal management capabilities given the -40°C to 105°C operational range.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is designed for vertical panel or through-hole mounting configurations. It represents a mature product line offering consistent quality for industrial interconnect solutions. The part number indicates specific row count, position total, and physical characteristics defined by the manufacturer.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variants like 305-052-520-201 for different mounting styles. Cross-referencing pin counts and pitch dimensions is essential when evaluating alternative manufacturers. Ensure any replacement maintains identical flange and polarizing key compatibility.
