305-026-520-268

Edgeboard Connectors Overview

The EDAC Inc. 305-026-520-268 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features a dual-row configuration with 26 positions and a contact spacing of 3.96 mm (0.156 inches). The row spacing is 3.56 mm, accommodating printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The contacts are made of copper alloy with a gold finish, rated for 5 A current at an insulation resistance of 5 GOhms. Operating temperatures range from -40°C to +105°C, and termination is achieved via solder pins.
