305-020-520-504

Edgeboard Connectors Overview

The EDAC Inc. 305-020-520-504 is a standard card edge connector featuring 20 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for PCB thicknesses of 1.57 mm. The component supports panel mount and through-hole installation with vertical orientation. Contacts are gold-plated copper alloy, rated for 5 A continuous current and 1800 VACrms dielectric strength. Operating temperature ranges from -40°C to +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

Accepts between-contact and in-contact polarizing keys for secure board retention
Dual-edge female contact design for reliable signal transmission
Gold-plated contacts ensure corrosion resistance and low contact impedance

Edgeboard Connectors Applications

Industrial control systems requiring robust card edge interfaces
Telecommunications equipment utilizing modular board architectures
Automotive electronics demanding high vibration resistance

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness, housing material variants, and packaging configurations. Ensure compatibility with existing polarizing key requirements and verify that the 1.57 mm board thickness specification matches the target application's PCB constraints before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, 20-position interface with a 3.96 mm pitch is required. It is suitable for applications needing panel mounting stability and high dielectric strength. Consider the 5 A current rating and wide temperature range for harsh environments. Verify that the vertical orientation fits within the mechanical enclosure constraints.

Edgeboard Connectors Part Context
