305-040-555-203

Edgeboard Connectors Overview

The EDAC Inc. 305-040-555-203 is a standard card edge connector from the 305 Series, designed for panel mount applications with a vertical orientation. It features 40 positions arranged in a dual-row configuration with a pitch of 3.96 mm (0.156 inches). The connector supports a board thickness of 1.57 mm and utilizes gold-plated copper alloy contacts for reliable signal transmission. Rated for 5 A continuous current, it employs a solder pin termination type to ensure secure electrical connections.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for enhanced alignment and security
• Dual-edge design accommodates specific card insertion requirements
• Thermoplastic housing provides structural integrity and insulation

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized modular connectors
• Test and measurement devices needing high-reliability panel-mounted connections

Edgeboard Connectors Procurement Notes

Verify the exact suffix against the manufacturer's latest datasheet to confirm plating thickness and material specifications. Ensure compatibility with the target PCB stack-up regarding the 1.57 mm thickness requirement. Confirm that the 40-position dual-row layout matches the mechanical constraints of the enclosure. Cross-reference the 3.96 mm pitch with mating card edge dimensions to prevent insertion force issues.

Edgeboard Connectors Selection Notes

Select this component when a 40-position dual-row interface is required for panel mounting. The 3.96 mm pitch offers a balance between density and spacing for industrial environments. Consider the gold plating for corrosion resistance in demanding conditions. Verify that the vertical installation style fits within the available chassis depth and height restrictions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which is a family of standard card edge connectors known for their versatility in industrial and commercial applications. The series offers various position counts and row configurations to suit different circuit board designs. The 305-040-555-203 specifically addresses the need for a 40-position connection point with a standard pitch.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC substitution guide for direct equivalents. Verify that any alternative maintains the 3.96 mm pitch and 40-position count. Ensure the replacement supports the same 5 A current rating and panel mount style. Check for compatibility with existing polarizing key requirements if applicable.
