305-054-500-578

Edgeboard Connectors Overview

The EDAC 305-054-500-578 is a standard card edge connector from the 305 series, designed for panel mount applications. It features 54 positions with a 3.96 mm (0.156 inch) contact spacing and dual rows. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Contacts are made of copper alloy with gold plating, rated for 5 A continuous current. The insulator body is green thermoplastic polyester, supporting an operating temperature range of -40°C to +105°C.
