305-012-555-204

Edgeboard Connectors Overview

The EDAC Inc. 305-012-555-204 is a standard card edge connector header featuring 12 positions with dual female contacts. It utilizes a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. Designed for .062 inch nominal thickness printed circuit boards, it employs gold-plated copper alloy contacts soldered via pin termination. The unit supports a continuous current rating of 5 A and withstands 1800 VACrms voltage. Constructed with a green thermoplastic insulator body, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features low profile insulator body construction for compact assembly
• Provides reliable electrical connection through gold-plated copper alloy contacts

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized board thicknesses
• Test and measurement instrumentation needing high-reliability connections

Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to ensure compatibility with your system requirements. Confirm that the 12-position configuration and 3.96 mm pitch match your PCB design specifications. Check for any updated environmental compliance certifications or packaging variations directly from the manufacturer before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 12 positions is required. Ensure the host PCB accommodates the specified 0.062 inch thickness and vertical panel mount style. Consider the 5 A current rating and 1800 VACrms insulation capability for appropriate electrical safety margins in your application design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options while maintaining consistent 3.96 mm spacing. These headers are designed for high-reliability applications requiring durable connections between edgeboards and backplanes or chassis-mounted sockets.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-012-555-502 if different housing colors or minor mechanical variations are acceptable. Verify that substitute parts maintain identical 12-position count, 3.96 mm pitch, and dual female contact configuration to ensure functional interchangeability.
