746-018-545-101

Edgeboard Connectors Overview

The EDAC Inc. 746-018-545-101 is a single-row card edge connector designed for press-fit installation onto printed circuit boards. It features 18 female contacts with a 0.125-inch (3.18mm) pitch and a 0.250-inch (6.35mm) row spacing. The connector utilizes cantilever contacts with gold plating, specifically 30.0µin (0.76µm) thickness, over copper alloy terminals. It accommodates card thicknesses between 0.054 inches and 0.070 inches (1.37mm to 1.78mm). The housing is black thermoplastic polyester, rated for operation from -40°C to 105°C.
