305-066-520-568

Edgeboard Connectors Overview

The EDAC Inc. 305-066-520-568 is a standard card edge connector designed for panel mount applications with a vertical orientation. It features a dual-row configuration providing 66 positions, calculated as 33 positions per row. The connector utilizes a 3.96 mm (0.156 inch) pitch between contacts. It is engineered to accept PCBs with a thickness ranging from 1.37 mm to 1.78 mm (0.054 to 0.070 inches). The contacts are constructed from copper alloy and feature a gold plating finish to ensure reliable electrical performance.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board retention
• Supports continuous current ratings of 5A with high dielectric strength
• Features thermoplastic insulation housing for durability

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• High-reliability computing hardware interfaces

Edgeboard Connectors Procurement Notes

Verify the specific pin count and row configuration against the target PCB design before procurement. Confirm that the mating card edge thickness falls within the specified mechanical limits. Ensure compatibility with polarizing key requirements if used in constrained spaces. Check RoHS compliance status for environmental regulations. Validate thermal operating range suitability for the intended application environment.

Edgeboard Connectors Selection Notes

Select this component when a high-current, double-sided card edge interface is required. The 3.96 mm pitch accommodates larger signal traces compared to finer pitches. Panel mounting provides stability for heavy or vibration-prone assemblies. Gold-plated contacts offer superior corrosion resistance for long-term reliability. Verify that the vertical orientation aligns with the chassis layout constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations to suit different density requirements. The 305 series is characterized by its rugged construction and high current carrying capacity. It is widely used in industrial and commercial applications demanding durable connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching pitch and row count. Cross-reference mechanical dimensions to ensure panel cutout compatibility. Verify that alternative parts support the same polarizing key options. Check for equivalent current and voltage ratings in replacement components.
