305-022-520-503

Edgeboard Connectors Overview

The EDAC Inc. 305-022-520-503 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 22 positions arranged in a dual row configuration with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts and a thermoplastic polyester insulator body. It supports a nominal printed circuit board thickness of 1.57 mm and offers a continuous current rating of 5 A.

Edgeboard Connectors Feature Summary

• Dual row female contact configuration for reliable signal transmission
• Gold-plated contacts ensure corrosion resistance and low contact impedance
• Thermoplastic polyester insulator provides structural stability and thermal endurance

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standardized card edge interfaces
• Test and measurement instrumentation needing high-reliability connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC datasheet to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with the target PCB thickness and polarizing key requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 22-position interface is required with a 3.96 mm pitch. Confirm that the application environment falls within the specified operating temperature range and that the 5 A current rating meets the electrical load requirements of the design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its .156 inch contact spacing and acceptance of .062 inch nominal PCB thickness. It is widely used in modular electronic systems where secure, solder-pin termination is necessary.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or flange styles. Verify mechanical footprint and electrical ratings match before substituting.
