305-078-555-504

Edgeboard Connectors Overview

The EDAC Inc. 305-078-555-504 is a standard card edge connector featuring 78 positions with dual female contacts. It utilizes a .156 inch (3.96 mm) contact spacing and a .140 inch (3.56 mm) row spacing. The unit accepts printed circuit boards with a nominal thickness of .062 inches (1.57 mm). Designed for panel mounting, it incorporates solder pin termination and gold-plated copper alloy contacts. The insulator body is constructed from green thermoplastic polyester, providing a low-profile configuration suitable for vertical installation.
