305-018-555-212

Edgeboard Connectors Overview

The EDAC Inc. 305-018-555-212 is a standard card edge connector header featuring 18 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and supports a maximum board thickness of 1.57 mm. The component employs gold-plated copper alloy contacts with a solder lug termination type for secure electrical connections. Designed for vertical panel mounting, it operates within a temperature range of -40°C to +105°C and maintains an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for precise alignment
• Provides a 5A continuous current rating with 1800VACrms dielectric strength
• Features thermoplastic polyester housing for durable insulation

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Panel-mounted electronic modules needing polarized connection options
• High-reliability communication equipment hardware

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to confirm contact plating thickness and termination style. Ensure compatibility with the target PCB thickness and polarizing key requirements before procurement. Confirm RoHS compliance status through the latest datasheet documentation.

Edgeboard Connectors Selection Notes

Select this model when vertical panel mounting and polarizing key support are required for 18-position dual-row applications. The 3.96mm pitch suits thicker circuit boards up to 1.57mm. Consider the 5A current rating and high voltage isolation for demanding industrial environments.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles designed for reliable interconnection in harsh environments. The 305 series is characterized by its thermoplastic polyester housing and copper alloy contact materials.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for direct substitutes with different position counts or termination types. Verify that alternative parts match the 3.96mm pitch and 1.57mm board thickness constraints.
