305-050-520-203

Edgeboard Connectors Overview

The EDAC Inc. 305-050-520-203 is a dual-row card edge connector designed for board-to-board or backplane interconnections. It features 50 positions with a 0.156-inch (3.96mm) contact spacing and a 0.140-inch (3.56mm) row spacing. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Constructed with copper alloy contacts finished with gold plating, it utilizes a thermoplastic insulator body. The component supports panel mounting and solder termination, operating within a temperature range of -40°C to +105°C.
