305-046-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-046-521-502 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 46 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 a thermoplastic insulator, supporting a continuous current rating of 5 A. It accommodates board thicknesses between 1.37 mm and 1.78 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for high-density signal routing
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Thermoplastic housing provides structural integrity and electrical insulation
• Accepts between-contact and in-contact polarizing keys for secure mating

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact plating thickness, housing color, and flange specifications. Ensure compatibility with existing PCB stack-up dimensions and polarizing key requirements before procurement. Confirm RoHS compliance status through manufacturer datasheets or certified component databases.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row card edge interface with a 3.96 mm pitch is required for panel-mounted assemblies. Consider the 5 A current rating and operating temperature range relative to the application's thermal environment. Verify that the target PCB thickness falls within the specified acceptance range to ensure proper mechanical retention and electrical contact.
