305-018-520-203

Edgeboard Connectors Overview

The EDAC 305-018-520-203 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features a dual-row configuration with 18 positions and a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). It utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and supports a continuous current rating of 5 A. The housing is constructed from thermoplastic material, providing durability in demanding environments.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Features a low-profile insulator body for compact assembly requirements
• Provides high dielectric strength with a 1800VACrms rating

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standardized card edge interfaces
• Test and measurement devices needing reliable high-voltage isolation

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and insulation material properties. Ensure that the ordering information matches the required row count and position quantity precisely. Cross-reference the mechanical dimensions with the target PCB layout to guarantee compatibility with the specified board thickness and mounting style.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with a 3.96 mm pitch is required for panel-mount applications. It is suitable for designs needing polarizing key acceptance and a 5 A current capacity. Consider the 1.57 mm board thickness constraint and the vertical orientation during the mechanical integration phase of the product development cycle.
