305-050-556-258

Edgeboard Connectors Overview

The EDAC Inc. 305-050-556-258 is a dual-edge female card edge connector designed for board-to-board interconnection. It features 50 positions arranged in two rows with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts with a thickness of 10.0 µin (0.25 µm) and half-beehive contact types. It supports printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and operates within a temperature range of -40°C to +105°C. The unit employs a straddle mount installation method and includes integrated card guides.
