305-068-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-068-521-258 is a standard card edge connector featuring 68 positions in a dual female configuration. It utilizes a 0.156-inch (3.96 mm) contact pitch and a 0.140-inch (3.56 mm) row spacing. Designed for panel installation, the unit accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The contacts are gold-plated copper alloy, providing a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The insulator body is constructed from thermoplastic material.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body design for compact integration
• Provides high dielectric strength with a 1800 VACrms rating

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standardized card edge interfaces
• Test and measurement instrumentation needing reliable signal transmission

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 68-position dual female configuration before procurement. Confirm that the application environment supports the specified temperature range and voltage ratings. Ensure compatibility with the intended PCB thickness of 0.062 inches to guarantee proper mechanical engagement and electrical continuity during operation.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection is required within a limited vertical space due to its low-profile design. Choose this model if the system requires acceptance of polarizing keys to prevent misalignment. Consider this connector for applications demanding a 5A current capacity and robust insulation properties in a panel-mount format.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its use of thermoplastic insulators and gold-plated contacts. This specific model represents a high-pin-count variant designed for dual-edge board connections, offering a balance of density and reliability for industrial-grade electronic assemblies.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-068-521-202 or 305-068-520-258 to verify identical pin counts and physical dimensions. Ensure that any substitute maintains the same 0.156-inch pitch and dual female contact type to preserve interface compatibility.
