305-078-500-258

Edgeboard Connectors Overview

The EDAC 305-078-500-258 is a standard card edge connector from the 305 Series, designed for panel mounting applications. It features a dual-row configuration with 78 positions and a 3.96 mm (0.156 inch) contact spacing. The connector utilizes gold-plated copper alloy contacts and accepts PCBs with thicknesses ranging from 1.37 mm to 1.78 mm. Rated for 5 A continuous current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design compatible with non-specified double-sided circuit boards
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Panel mount style with vertical orientation for secure installation
• Accepts between-contact and in-contact polarizing keys for board alignment

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing double-sided PCBs
• Test and measurement instrumentation interfaces
• Automotive electronics modules needing high-current connections

Edgeboard Connectors Procurement Notes

Verify that the target application supports the specified 3.96 mm pitch and 78-position count. Confirm compatibility with the required PCB thickness range of 1.37 mm to 1.78 mm. Ensure the system environment remains within the operational temperature limits of -40°C to +105°C. Check for any specific polarizing key requirements if board alignment is critical to the assembly process.

Edgeboard Connectors Selection Notes

Select this component when a high-density, double-row connection is necessary for thick PCBs. The 5 A current rating makes it suitable for power distribution or high-load signal lines. Consider the green thermoplastic insulator material for environmental resistance. This series offers a standardized footprint for easy integration into existing panel designs.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides a range of card edge connectors for various position counts and pitches. The series is known for its durability and consistent performance in demanding environments. Similar parts in the series vary by position count and contact plating options.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 Series variants with matching 78 positions and 3.96 mm pitch, such as 305-078-500-508, provided the end termination type matches the assembly requirements.
