305-052-556-502

Edgeboard Connectors Overview

The EDAC Inc. 305-052-556-502 is a dual-edge female card edge connector designed for board-to-board interconnection. It features 52 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 featuring gold plating, it utilizes a thermoplastic insulator body. The component supports solder termination and panel mount installation, operating within a temperature range of -40°C to +105°C.
