305-080-500-278

Edgeboard Connectors Overview

The EDAC Inc. 305-080-500-278 is a standard card edge connector receptacle featuring 80 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing. Designed for PCB mounting, this component accepts printed circuit boards with a nominal thickness of 1.57 mm. The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. Rated for 5 A continuous current, the connector operates within a temperature range of -40°C to +105°C.
