305-044-556-507

Edgeboard Connectors Overview

The EDAC Inc. 305-044-556-507 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 44 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The contacts are gold-plated copper alloy, rated for 5 A current, while the tails utilize tin plating over nickel underplating for soldering. The housing is green thermoplastic, supporting PCB thicknesses of 1.37 mm to 1.78 mm. Operating temperatures range from -40°C to +105°C.
