305-040-520-502

Edgeboard Connectors Overview

The EDAC Inc. 305-040-520-502 is a standard card edge connector header from the 305 series, designed for panel mount installation with a vertical orientation. It features 40 positions arranged in two rows with a pitch of 3.96 mm (0.156 inches). The connector accommodates board thicknesses of 1.57 mm and utilizes gold-plated copper alloy contacts rated for 5 A current. Termination is achieved via solder lug pins, and the thermoplastic housing provides an insulation resistance of 5 GOhms across an operating temperature range of -40°C to +105°C.
