305-052-555-278

Edgeboard Connectors Overview

The EDAC Inc. 305-052-555-278 is a standard card edge connector featuring 52 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component employs female contacts with gold plating and copper alloy construction, rated for 5 A current at 105°C maximum operating temperature. Designed for vertical panel mounting via solder lug termination, it offers an insulation resistance of 5 GOhms and operates within a temperature range of -40°C to +105°C.
