305-086-521-204

Edgeboard Connectors Overview

The EDAC Inc. 305-086-521-204 is a standard card edge connector receptacle featuring 86 positions in a dual-row configuration. It utilizes a 0.156-inch (3.96 mm) contact spacing with a 0.140-inch (3.56 mm) row spacing. Designed for panel mounting, this component accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. Rated for 5 amperes, the connector supports an operating temperature range of -40°C to +105°C.
