305-072-556-278

Edgeboard Connectors Overview

The EDAC Inc. 305-072-556-278 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 72 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum current rating of 5 A. The contacts are made of copper alloy with gold plating, terminated via solder pins for secure PCB mounting. The housing utilizes thermoplastic polyester insulation, providing reliable performance across an operating temperature range of -40°C to +105°C.
