305-022-520-501

Edgeboard Connectors Overview

The EDAC Inc. 305-022-520-501 is a standard card edge connector featuring 22 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and supports a maximum operating temperature of +105°C with a minimum of -40°C. The component employs gold-plated copper alloy contacts for reliable signal transmission and offers an insulation resistance of 5 GOhms. Designed for panel mounting at a vertical angle, it accommodates PCBs with a thickness of 1.57 mm. The unit provides a current rating of 5 A and uses solder pin termination for secure board attachment.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact plating thickness, material specifications, and compliance certifications. Ensure that the selected variant matches the required PCB thickness and mounting orientation for your design. Cross-reference the part number with the latest datasheet to confirm availability status and any potential obsolescence notices before finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with a 3.96 mm pitch is required for vertical panel mounting. Ensure the application environment remains within the specified -40°C to +105°C operating range. Verify that the target PCB thickness aligns with the 1.57 mm specification to guarantee proper mechanical engagement. Confirm that the 5 A current rating and 5 GOhms insulation resistance meet the system's electrical requirements.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts, with dual-row configurations available up to 86 contacts upon request. The 305 series is characterized by its robust thermoplastic housing and gold-plated contacts, making it suitable for demanding industrial and commercial applications requiring reliable interconnectivity.

Edgeboard Connectors Replacement Considerations
