305-036-520-278

Edgeboard Connectors Overview

The EDAC Inc. model 305-036-520-278 is a standard card edge connector header featuring 36 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row pitch. Designed for panel mounting at a vertical angle, the unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. Rated for 5 A current, the connector operates within a temperature range of -40°C to +105°C and provides an insulation resistance of 5 GOhms.
