305-082-521-508

Edgeboard Connectors Overview

The EDAC Inc. 305-082-521-508 is a dual-edge female card edge connector designed for panel mount and through-hole termination. It features 82 positions with a 0.156-inch (3.96mm) contact spacing across two rows. The contacts are made of copper alloy with a gold plating thickness of 10.0µin (0.25µm). The connector accommodates card thicknesses between 0.054 inches and 0.070 inches (1.37mm to 1.78mm). It utilizes a thermoplastic polyester insulator and operates within a temperature range of -40°C to 105°C.
