387-068-521-212

Edgeboard Connectors Overview

The EDAC Inc. 387-068-521-212 is a standard card edge connector designed for through-hole mounting with solder termination. It features a dual-edge female configuration with 68 positions and a contact spacing of 0.156 inches (3.96 mm). The connector utilizes copper alloy contacts with a gold finish, specifically 10.0 µin (0.25 µm) thick, to ensure reliable signal transmission. The insulating body is constructed from thermoplastic polyester, providing stability within an operating temperature range of -40°C to +105°C. This component supports printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm), offering a robust mechanical interface for high-density electronic assemblies.

Edgeboard Connectors Feature Summary
