306-015-521-104

Edgeboard Connectors Overview

The EDAC Inc. 306-015-521-104 is a dual-edge female card edge connector designed for panel and through-hole mounting. It features 30 positions with a 0.156-inch (3.96mm) contact spacing arranged in two rows. The contacts are made of copper alloy with gold plating, utilizing a cantilever design for reliable signal transmission. The insulator body is green thermoplastic polyester, supporting PCB thicknesses between 0.054 and 0.070 inches. Rated for operation from -40°C to 105°C, it includes a flange with top openings and 4-40 threaded inserts for secure installation.
