305-078-520-268

Edgeboard Connectors Overview

The EDAC Inc. 305-078-520-268 is a standard card edge connector featuring 78 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 5.08 mm (0.200 inch) row spacing. The component supports a nominal printed circuit board thickness of 1.57 mm (0.062 inch). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are constructed from copper alloy with gold plating, housed in a green thermoplastic insulator body. Operating temperature ranges from -40 C to +105 C.
