305-030-555-278

Edgeboard Connectors Overview

The EDAC Inc. 305-030-555-278 is a standard card edge connector from the 305 Series, designed for vertical panel mounting applications. It features a dual-row configuration with 30 positions and a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. It is engineered to accept printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The unit supports a continuous current rating of 5 A and withstands voltages up to 1800 VACrms. Operating within a temperature range of -40°C to +105°C, it employs a thermoplastic insulator body and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from thermoplastic material
• Provides high dielectric strength with a 1800 VACrms voltage rating

Edgeboard Connectors Applications

• Vertical panel-mounted electronic assemblies requiring robust interconnection
• Systems utilizing polarizing keys for precise board insertion guidance
• High-voltage signal routing environments demanding strict insulation standards

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 30-position dual-row specification. Confirm compatibility with 1.57 mm PCB thicknesses before integration. Ensure that the application environment remains within the specified -40°C to +105°C operating temperature range. Check for availability of compatible polarizing keys if mechanical locking is required for the assembly process.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount interface is necessary for double-sided edge cards. The 3.96 mm pitch suits applications where standard industrial spacing is preferred over finer pitches. Consider the 5 A current capacity for power distribution needs alongside signal lines. The gold plating ensures durability against corrosion in varied environmental conditions.

Edgeboard Connectors Part Context

This model belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series is characterized by its .156 inch contact spacing and compatibility with .062 inch nominal PCB thicknesses. These connectors are widely used in industrial and commercial electronics where reliable, high-density connections are essential for system integrity.

Edgeboard Connectors Replacement Considerations

Cross-reference other 305 Series variants with identical pin counts and row configurations. Verify that any substitute maintains the same 3.96 mm pitch and 1.57 mm board thickness tolerance. Ensure the replacement also supports the required vertical panel mounting style and gold contact finish.
