305-040-521-503

Edgeboard Connectors Overview

The EDAC Inc. 305-040-521-503 is a standard card edge connector from the 305 series, designed for panel mounting with a vertical orientation. It features a dual-row configuration with 40 positions and a 3.96 mm pitch. The contacts are made of copper alloy with gold plating, rated for 5 A current. It accepts board thicknesses between 1.37 mm and 1.78 mm (0.054" to 0.070"). The housing is green thermoplastic polyester, supporting an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for non-specified dual-edge card acceptance
• Gold-plated copper alloy contacts ensure reliable electrical connection
• Thermoplastic polyester insulator provides structural stability and thermal resistance

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Communication equipment utilizing dual-edge circuit boards
• Automotive electronics applications demanding high current capacity

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to confirm exact pin count, row configuration, and termination style. Ensure the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range for proper mechanical engagement. Confirm RoHS compliance status if required by project specifications before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for dual-edge cards. The 3.96 mm pitch accommodates larger spacing requirements compared to finer pitches. The 5 A rating supports moderate power distribution needs. Verify that the application environment stays within the -40°C to +105°C operational limits for long-term reliability.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series, which offers various mounting styles and position counts. The series is characterized by its use of thermoplastic materials and gold-plated contacts. It serves as a standardized interface for connecting double-sided printed circuit boards in industrial and commercial electronic assemblies.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for direct substitutes with different position counts or mounting angles. Cross-reference compatible parts from other manufacturers only if they match the 3.96 mm pitch and dual-row specification exactly.
