305-044-521-558

Edgeboard Connectors Overview

The EDAC Inc. 305-044-521-558 is a dual-row card edge connector designed for panel and through-hole mounting. It features 44 positions with a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches. The connector utilizes gold-plated copper alloy contacts with a 10.0µin plating thickness, housed in a green thermoplastic polyester insulator. Rated for 5A continuous current and 1800VACrms dielectric strength, it operates within a temperature range of -40°C to +105°C.
