305-068-520-278

Edgeboard Connectors Overview

The EDAC Inc. 305-068-520-278 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 68 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum PCB thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and includes in-line card guides for secure mounting. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic material, providing robust insulation and mechanical stability for vertical panel installation applications.

Edgeboard Connectors Feature Summary

• Dual-row configuration with gold-plated copper alloy contacts for enhanced conductivity
• Integrated in-line card guides facilitate precise alignment and secure board retention
• Thermoplastic insulator provides stable electrical isolation and environmental protection

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Medical device internal circuitry connections
• Automotive electronic module interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating thickness, housing color, and termination style. Ensure the selected variant matches the required PCB thickness and mounting orientation for your specific assembly design before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with a 3.96 mm pitch is required. Confirm that the application environment stays within the specified -40°C to +105°C operating temperature range. Verify that the PCB design accommodates the 1.57 mm maximum thickness and that the panel mounting style aligns with the system chassis requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its use of thermoplastic housings and solder pin terminations. It is distinct from high-temperature variants like the 845 series or fine-pitch options, offering a balance of standard spacing and durable construction for general-purpose industrial and commercial electronics.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical position counts and pitch, such as the 305-068-520-268. When replacing, verify that the new part maintains the same dual-row formation, vertical mounting angle, and compatible PCB thickness specifications to ensure mechanical and electrical compatibility.
