305-042-520-208

Edgeboard Connectors Overview

The EDAC Inc. 305-042-520-208 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 42 positions with a 3.96 mm (0.156 inch) pitch and accepts dual-edge non-specified cards. The connector utilizes gold-plated copper alloy contacts with a half-wave spring termination type, rated for 5 A continuous current and 1800 VACrms insulation. It supports board thicknesses between 1.37 mm and 1.78 mm, operates within a -40°C to +105°C temperature range, and includes flange features for flush installation.
