305-020-520-268

Edgeboard Connectors Overview

The EDAC 305-020-520-268 is a standard card edge connector featuring 20 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component employs gold-plated copper alloy contacts to ensure reliable signal transmission, supporting a continuous current rating of 5 A. Designed for panel mounting in a vertical orientation, it offers an insulation resistance of 5 GOhms and operates within a temperature range of -40°C to +105°C.

• Dual-row female connector design accepting standard .062 inch thick PCBs
• Gold-plated contacts on copper alloy substrate for corrosion resistance
• Compatible with between-contact and in-contact polarizing keys
• Vertical panel mount installation style

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm exact plating thickness, insulator color, and termination type compatibility. Ensure that the selected variant matches the required board thickness and polarizing key specifications for the target application environment.

Edgeboard Connectors Selection Notes

Select this connector when a robust dual-row interface is required for .062 inch thick circuit boards. The 3.96 mm pitch accommodates high-density layouts while maintaining electrical isolation. Consider the vertical panel mount form factor for chassis integration where space efficiency and secure mechanical locking are priorities.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its durable thermoplastic polyester insulator body and standardized dimensions. The 305 series provides a versatile solution for connecting plug-in cards to motherboards or backplanes in various electronic assemblies.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers such as 305-020-520-568 or 305-020-500-203 for alternative configurations within the same family. Verify that any substitute maintains the identical 20-position count, 3.96 mm pitch, and dual-row architecture to ensure mechanical and electrical interchangeability.
