305-028-556-208

Edgeboard Connectors Overview

The EDAC Inc. 305-028-556-208 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 28 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic housing. It supports a continuous current rating of 5 A and operates within a temperature range of -40°C to +105°C. The unit accepts board thicknesses between 1.37 mm and 1.78 mm and employs a solder lug termination method.
