305-020-520-208

Edgeboard Connectors Overview

The EDAC Inc. 305-020-520-208 is a standard card edge connector from the 305 series, designed for vertical panel mounting applications. It features a dual-edge female configuration with 20 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal 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, while the insulator body is made of green thermoplastic polyester. Operating temperatures range from -40°C to +105°C.
