305-032-500-278

Edgeboard Connectors Overview

The EDAC Inc. 305-032-500-278 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 32 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum operating temperature of +105°C and a minimum of -40°C. The connector utilizes gold-plated copper alloy contacts and a thermoplastic insulation material. It is rated for 5 A current and offers an insulation resistance of 5 GOhms. The unit employs a solder lug termination type and is intended for panel mounting in a vertical orientation.

Edgeboard Connectors Feature Summary

• Dual-edge configuration with 32 positions for robust signal transmission
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Thermoplastic insulation provides stable performance across wide temperature ranges
• Panel mount design with vertical orientation for secure mechanical integration

Edgeboard Connectors Applications

• Industrial control systems requiring high-reliability interconnects
• Telecommunications equipment utilizing dual-edge card architectures
• Test and measurement devices needing standardized card edge interfaces
• Automotive electronics modules operating in varied thermal environments

Edgeboard Connectors Procurement Notes

Verify that the specific suffix 278 corresponds to the threaded insert flange feature (4-40) as indicated by distributor data. Confirm that the solder lug termination matches the target PCB layout requirements. Ensure the thermoplastic insulation material meets the environmental standards required for the final assembly. Cross-reference the 5 A current rating against the actual load conditions to prevent overheating during operation.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connector with a 3.96 mm pitch is required for panel-mounted applications. The 32-position count suits moderate-density interface needs. The vertical installation style and solder lug termination dictate the mechanical assembly approach. Consider the -40°C to +105°C operating range for suitability in harsh environments compared to standard commercial grade alternatives.

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 insulation and copper alloy contacts. The 305 series typically supports various position counts and termination styles, allowing for flexible integration into different electronic assemblies while maintaining consistent electrical performance characteristics.

Edgeboard Connectors Replacement Considerations

The 305-032-500-203 is a related variant within the same series but differs in flange features, lacking the threaded inserts found in the 278 suffix. Verify mechanical compatibility before substitution, as the mounting hardware requirements will differ significantly between these two part numbers.
