305-084-555-568

Edgeboard Connectors Overview

The EDAC Inc. 305-084-555-568 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 84 positions with a 3.96 mm (0.156 inch) pitch and supports two rows of contacts. The connector utilizes gold-plated copper alloy terminals with a half-bean spring contact type, rated for 5 A continuous current. It accommodates PCB thicknesses between 1.37 mm and 1.78 mm and employs a straddle mount installation style. The thermoplastic housing provides insulation resistance of 5 GOhms and operates within a temperature range of -40°C to +105°C.
