305-084-500-508

Edgeboard Connectors Overview

The EDAC Inc. 305-084-500-508 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 84 positions with a 0.156-inch (3.96 mm) pitch and supports a maximum operating temperature of +105°C. The connector utilizes gold-plated copper alloy contacts with a half-beam termination style for reliable signal transmission. Insulation is provided by thermoplastic material, ensuring an insulation resistance of 5 GOhms. It operates within a temperature range of -40°C to +105°C and accepts PCB thicknesses between 1.37 mm and 1.78 mm.
