305-020-520-508

Edgeboard Connectors Overview

The EDAC 305-020-520-508 is a standard card edge connector featuring 20 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component provides a continuous current rating of 5 A and supports 1800 VACrms insulation voltage. Contacts are gold-plated copper alloy, ensuring reliable conductivity. The housing is constructed from green thermoplastic polyester, offering durability within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Dual-edge design facilitates connection to both sides of the card edge
