306-020-521-168

Edgeboard Connectors Overview

The EDAC Inc. 306-020-521-168 is a dual-edge female card edge connector from the 306 Series, designed for panel and through-hole mounting. It features 20 positions with a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The contacts are made of copper alloy with gold plating, utilizing a cantilever spring type for reliable engagement. The insulator body is constructed from thermoplastic polyester and is colored green. This component supports a wide operating temperature range from -40°C to +105°C and includes flange features for secure installation.
