305-084-520-507

Edgeboard Connectors Overview

The EDAC Inc. 305-084-520-507 is a standard card edge connector designed for high-density vertical panel mounting applications. It features 84 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and accepts PCBs with thicknesses between 1.37 mm and 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

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Provides 1800VACrms dielectric voltage withstand capability
• Features half-beam contact type for reliable board retention

Edgeboard Connectors Applications

• High-density electronic module interconnects
• Industrial control system backplanes
• Telecommunications equipment interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required polarization keys and termination styles. Confirm that the target printed circuit board thickness falls within the specified 1.37 mm to 1.78 mm range prior to integration. Cross-reference the 84-position configuration with mechanical constraints to ensure proper panel fitment.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, high-pin-count interface is required for vertical panel mounting. The 3.96 mm pitch accommodates larger signal traces compared to finer pitches. Ensure the application environment remains within the -40°C to +105°C operating limits and requires the specified 5 A current rating per contact.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by robust thermoplastic housings and semi-beam or half-beam contact designs suitable for repeated mating cycles. The 305 series supports various position counts and polarization options for diverse industrial and commercial applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include other 305-series variants with matching 84 positions and 3.96 mm pitch, such as 305-084-520-508, provided the termination style and insulation material are compatible.
