305-018-520-212

Edgeboard Connectors Overview

The EDAC Inc. 305-018-520-212 is a standard card edge connector header from the 305 Series. It features an 18-position configuration with a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. Designed for vertical panel mount installation, it accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are gold-plated copper alloy, rated for 5 A continuous current. The insulator body is green thermoplastic polyester, supporting a voltage rating of 1800 VACrms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Low profile insulator body design for compact integration
• Gold-plated contacts ensure reliable electrical performance

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard PCB thicknesses
• Automotive electronics modules needing high voltage isolation

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating, insulator color, and termination style match the application requirements. Ensure the selected variant supports the required PCB thickness of 1.57 mm. Confirm that the panel mount orientation aligns with the mechanical enclosure design before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 3.96 mm pitch is required for vertical mounting. It is suitable for applications demanding 5 A current capacity and 1800 VACrms insulation resistance. Consider the polarizing key compatibility if precise board insertion guidance is necessary for the assembly process.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors. The series offers various position counts and termination styles while maintaining consistent 3.96 mm spacing. These connectors are designed for general-purpose electronic applications where reliable signal transmission and mechanical stability are critical for long-term operation.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-040-520-268 or 305-038-520-502 for different position counts. Verify that substitute parts maintain the same 3.96 mm pitch and 1.57 mm board thickness acceptance to ensure mechanical compatibility.
