306-032-521-178

Overview

The EDAC Inc. 306-032-521-178 is a dual-edge female card edge connector from the 306 Series, designed for board-to-board interconnection. It features 64 positions with a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The connector utilizes cantilever contacts made of copper alloy with gold plating for reliable signal transmission. It employs a solder termination method and is housed in a green polyamide (PA66) insulator body. The component operates within a temperature range of -55°C to 85°C and is classified as a standard edgeboard connector suitable for various industrial applications.
