305-042-500-268

Edgeboard Connectors Overview

The EDAC 305-042-500-268 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 42 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and accepts board thicknesses between 1.37 mm and 1.78 mm. Rated for 5 A continuous current, it operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, ensuring reliable electrical performance in industrial applications.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Provides 1800VACrms dielectric voltage capability
• Features solder lug termination for robust panel installation

Edgeboard Connectors Applications

• Industrial control systems requiring high-voltage isolation
• Panel-mounted electronic interfaces
• Communication equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Confirm that the required polarizing key type matches the connector's acceptance criteria. Ensure the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range for proper contact engagement. Cross-reference the operating temperature requirements with the component's rated range of -40°C to +105°C.

Edgeboard Connectors Selection Notes

Select this model when a dual-row card edge connector with a 3.96 mm pitch is required for panel-mount applications. The 42-position count suits moderate-density interconnect needs. Consider the 5 A current rating and 1800VACrms insulation strength for circuits demanding higher electrical isolation. Verify compatibility with existing polarizing key systems if mechanical alignment is critical.

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, all sharing common design principles such as vertical mounting and durable thermoplastic housings. The 305-042-500-268 variant specifically addresses applications needing 42 contacts with gold-plated contacts for corrosion resistance.

Edgeboard Connectors Replacement Considerations

Consult official EDAC cross-reference guides for verified substitutes. No direct third-party equivalents are confirmed in public documentation. Ensure any replacement maintains the 3.96 mm pitch, 42-position count, and dual-row configuration.
