305-012-555-203

Edgeboard Connectors Overview

The EDAC Inc. 305-012-555-203 is a standard card edge connector from the 305 Series, designed for dual-edge board applications. It features 12 positions with a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Constructed with copper alloy contacts featuring gold plating, it supports a current rating of 5 A. The insulator body is made of thermoplastic polyester, colored green, and operates within a temperature range of -40°C to +105°C.
