305-038-521-208

Edgeboard Connectors Overview

The EDAC Inc. 305-038-521-208 is a standard card edge connector from the 305 Series, designed for panel mounting applications. It features a dual row configuration with 38 positions and a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts with a half-beam termination type, ensuring reliable electrical performance. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. The insulator body is green thermoplastic polyester, accepting printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm).

Edgeboard Connectors Feature Summary

• Dual row female connector design with half-beam contact type for secure board retention.
• Gold-plated copper alloy contacts provide corrosion resistance and stable conductivity.
• Thermoplastic polyester insulator body supports vertical panel mounting configurations.

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects.
• Telecommunications equipment utilizing standard card edge interfaces.
• Test and measurement instrumentation needing high-reliability signal paths.

Edgeboard Connectors Procurement Notes

Verify that the specific suffix 208 corresponds to the required flange and termination details in the official datasheet. Confirm RoHS compliance status and environmental ratings match project requirements before ordering. Ensure compatibility with the target PCB thickness of 1.57 mm to guarantee proper mechanical fit and electrical connection integrity during assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 38-position interface is required for panel-mount installations. The 3.96 mm pitch accommodates standard board layouts while the 5 A rating suits moderate power applications. Consider the green thermoplastic housing for visual identification and the specified operating temperature range for environmental durability in controlled settings.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various position counts and mounting styles. The series is characterized by its standardized dimensions and reliable performance in industrial environments. Similar parts in the series differ primarily in position count, such as the 305-030 or 305-040 variants, allowing for scalable design options within the same connector family.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 Series connectors with identical 38-position dual-row specifications. Verify that any alternative maintains the 3.96 mm pitch and 1.57 mm board thickness acceptance. Cross-reference flange dimensions and termination types to ensure mechanical compatibility with existing panel cutouts and soldering processes.
