305-050-521-208

Edgeboard Connectors Overview

The EDAC 305-050-521-208 is a standard card edge connector featuring 50 positions in a dual female configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 5.08 mm row spacing. Designed for .062 inch (1.57 mm) nominal thickness printed circuit boards, the unit accepts between-contact and in-contact polarizing keys. The connector provides a 5A continuous current rating and supports 1800VACrms dielectric strength. It employs gold-plated copper alloy contacts within a green thermoplastic polyester insulator body.
