305-066-521-501

Edgeboard Connectors Overview

The EDAC Inc. 305-066-521-501 is a dual-edge female card edge connector designed for through-hole mounting. It features 66 positions with a 0.156-inch (3.96mm) pitch across two rows. The contacts are made of copper alloy with gold plating and utilize a semi-crimping termination method. The insulator is constructed from green thermoplastic polyester, supporting board thicknesses between 0.054 and 0.070 inches. Rated for operation from -40°C to 105°C, it complies with RoHS3 standards.
