305-044-555-512

Edgeboard Connectors Overview

The EDAC Inc. 305-044-555-512 is a standard card edge connector from the 305 Series, designed for panel mount applications with a vertical orientation. It features 44 positions arranged in a dual row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes copper alloy contacts with gold plating and a thermoplastic polyester insulator. It supports solder pin termination and accommodates board thicknesses between 1.37 mm and 1.78 mm. The unit is rated for 5 A continuous current and operates within a temperature range of -40°C to +105°C.
