305-046-520-512

Edgeboard Connectors Overview

The EDAC Inc. 305-046-520-512 is a standard card edge connector from the 305 series, designed for panel mount installation with a vertical orientation. It features 46 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes copper alloy contacts with gold plating and accepts board 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 and employs a thermoplastic polyester insulator.

• Provides 1800 VACrms dielectric strength capability
• Features half-beam contact type for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Medical device internal circuit boards

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to ensure correct pin count, contact plating thickness, and flange specifications. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies by region. Cross-reference the datasheet drawing for precise mounting hole dimensions and mechanical tolerances before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge female connector with a 3.96 mm pitch is required for panel-mounted applications. Ensure the target PCB thickness falls within the 1.37 mm to 1.78 mm acceptance range. Consider the 5 A current rating and 105°C maximum operating temperature for thermal management requirements. Verify compatibility with existing polarizing key systems if used in high-vibration environments.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and mounting styles, providing a standardized solution for connecting double-sided printed circuit boards. The 305 series is known for its robust construction and reliable performance in demanding environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include part numbers such as 305-048-520-512 and 305-038-520-502, which share identical mechanical and electrical characteristics but differ in position count. Always verify that any replacement maintains the same pitch, row configuration, and current rating to ensure functional equivalence.
