305-018-520-512

Edgeboard Connectors Overview

The EDAC Inc. 305-018-520-512 is a standard card edge connector header featuring 18 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for vertical panel mount installation. The contacts are constructed from copper alloy with gold plating, supporting a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The unit accommodates board thicknesses within the 1.37 mm to 1.78 mm range and operates between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Provides high dielectric strength with 1800VACrms insulation capability
• Features thermoplastic polyester housing for environmental stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Communication equipment utilizing standardized card edge interfaces
• Test and measurement devices needing reliable dual-edge signal paths

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC channels or certified distributors. Confirm RoHS compliance status and specific packaging quantities prior to order placement. Ensure compatibility with existing polarizing key requirements and panel mounting specifications to avoid integration issues during assembly.

Edgeboard Connectors Selection Notes

Select this model when a 18-position dual-row interface is required with a 3.96 mm pitch. It is suitable for applications demanding vertical panel mounting and gold-plated contacts for corrosion resistance. Consider the 5A current rating and wide temperature range for harsh environment deployments where standard headers may fail.

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, maintaining consistent dimensional standards and electrical ratings across the family. This specific part number denotes the 18-position variant with solder pin termination and gold contact finish.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305-series parts sharing the same 3.96 mm pitch and dual-row layout. Verify mechanical fitment and electrical ratings against alternatives like the 305-018-555-208 if termination style differences are acceptable. Ensure polarizing key compatibility remains unchanged.
