305-066-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-066-521-502 is a dual female card edge connector featuring 66 positions with a 0.156-inch (3.96mm) pitch. It utilizes half-bevel contacts made of copper alloy with a gold finish, specifically 10.0µin (0.25µm) thick. Designed for through-hole mounting and solder termination, the connector supports non-specified dual-edge cards within a thickness range of 0.054 to 0.070 inches. The housing is constructed from green thermoplastic polyester, ensuring reliable performance across an operating temperature range of -40°C to +105°C.
