305-086-521-568

Edgeboard Connectors Overview

The EDAC Inc. 305-086-521-568 is a standard card edge connector from the 305 series, designed for high-reliability interconnection applications. It features 86 positions with a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. The component accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). It utilizes gold-plated copper alloy contacts to ensure stable electrical performance and offers a continuous current rating of 5 A with a dielectric withstand voltage of 1800 VACrms. The connector employs a low-profile insulator body and supports both between-contact and in-contact polarizing keys for secure mating alignment.
