305-012-520-508

Edgeboard Connectors Overview

The EDAC 305-012-520-508 is a standard card edge connector featuring 12 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a row pitch of 3.56 mm (0.140 inch). Designed for .156 inch (3.96 mm) nominal thickness printed circuit boards, the unit accepts between-contact and in-contact polarizing keys. The contacts are gold-plated copper alloy, rated for 5 A continuous current and 1800 VACrms insulation voltage. The insulator body is constructed from thermoplastic material.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features low profile insulator body construction
• Utilizes gold-plated copper alloy contacts for reliable conductivity

Edgeboard Connectors Applications

• Electronic module interconnection systems
• Industrial control panel interfaces
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Confirm that the selected variant matches the required polarizing key acceptance capabilities for the intended assembly process.

Edgeboard Connectors Selection Notes

Select this component when a dual-row connection with 3.96 mm spacing is required for 1.57 mm thick boards. The 12-position count suits compact interface applications. Verify that the 5 A current rating and 1800 VACrms insulation requirements align with the system design parameters prior to final selection.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts while maintaining consistent 3.96 mm contact spacing. The 305-012-520-508 specifically addresses applications requiring a 12-position dual-row interface with gold-plated contacts and thermoplastic housing.

Edgeboard Connectors Replacement Considerations

Cross-reference other EDAC 305 series variants with matching 12-position dual-row configurations. Ensure any substitute maintains the 3.96 mm pitch and 1.57 mm board thickness compatibility. Verify identical polarizing key acceptance features if mechanical locking is required.
