305-018-521-568

Edgeboard Connectors Overview

The EDAC Inc. 305-018-521-568 is a standard card edge connector from the 305 Series, designed for dual-edge board applications. It features 18 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector utilizes female contacts made of copper alloy with gold plating and employs a solder lug termination type. Designed for panel mounting at a vertical angle, it accommodates PCB thicknesses ranging from 1.37 mm to 1.78 mm. The insulator is constructed from green thermoplastic polyester, ensuring reliable performance within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Solder lug termination style for secure panel installation
• Thermoplastic polyester insulator housing rated for high temperatures

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules
• Automotive electronic subsystems

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact contact geometry and flange specifications. Ensure compatibility with the target PCB thickness limits before procurement. Confirm RoHS compliance status through current manufacturer declarations. Cross-reference the part number with authorized distributors to validate authenticity and traceability.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 18-position interface is required for vertical panel mounting. The 3.96 mm pitch suits applications needing robust mechanical retention. Verify that the mating card edge thickness falls within the specified 1.37 mm to 1.78 mm range. Consider the solder lug termination requirement for the assembly process.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides a range of standard card edge connectors. The series offers various position counts and mounting styles, all sharing common design principles such as gold-plated contacts and thermoplastic insulation. This specific model represents a mid-range position count option within the series.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 Series variants with identical 18-position dual-row configurations. Verify mechanical dimensions and pinout compatibility before substitution. Alternative manufacturers may offer similar specs but require thorough validation of contact material and plating thickness.
