305-046-520-278

Edgeboard Connectors Overview

The EDAC Inc. 305-046-520-278 is a standard card edge connector from the 305 series, designed for panel-mounted vertical installation. It features a dual-edge configuration with 46 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and supports PCB thicknesses of 1.57 mm. Contacts are constructed from copper alloy with gold plating, rated for 5 A current and offering 5 GOhms insulation resistance. The thermoplastic housing ensures durability within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided card edges for robust signal transmission.
• Vertical panel mount style provides secure structural integration into equipment enclosures.
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance over time.

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, termination type, and housing color variations. Ensure compatibility with target PCB thickness specifications before procurement. Cross-reference RoHS compliance status with current manufacturer declarations to meet regulatory requirements for the intended deployment region.

Edgeboard Connectors Selection Notes

Select this component when a high-density vertical connection is required for double-sided circuit boards. The 3.96 mm pitch offers spacing suitable for higher voltage isolation compared to finer pitches. Verify that the 5 A current rating aligns with the application's power distribution needs and that the panel mount form factor fits the mechanical constraints of the assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in position counts and mounting styles. The 305 series typically employs thermoplastic housings and solder pin terminations, providing a balance of electrical performance and mechanical stability for general-purpose industrial and commercial electronic applications requiring reliable board-to-board or board-to-backplane connections.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts such as 305-040-520-268 or 305-054-556-278. Ensure replacement parts maintain identical pitch, row configuration, and mounting orientation to preserve mechanical fit and electrical interface compatibility without redesigning the host enclosure.
