305-034-520-208

Edgeboard Connectors Overview

The EDAC Inc. 305-034-520-208 is a standard card edge connector from the 305 Series, designed for panel mount applications with vertical orientation. It features 34 positions arranged in a dual row configuration with a pitch of 3.96 mm (0.156 inches). The connector accommodates a board thickness of 1.57 mm and utilizes gold-plated copper alloy contacts for reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms dielectric strength, it operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic material, providing an insulation resistance of 5 GOhms.
