305-054-556-204

Edgeboard Connectors Overview

The EDAC Inc. 305-054-556-204 is a standard card edge connector from the 305 series, designed for dual-edge female applications. It features 54 positions with a 3.96 mm (0.156 inch) pitch and supports board thicknesses of 1.37 mm to 1.78 mm. The contacts are gold-plated copper alloy with a 10.0 µin thickness, rated for 5 A current. Operating within -40°C to +105°C, it utilizes thermoplastic polyester insulation and offers 5 GOhms insulation resistance.
