305-016-556-204

Edgeboard Connectors Overview

The EDAC Inc. 305-016-556-204 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 16 positions with a 3.96 mm (0.156 inch) pitch and supports two contact rows. The connector utilizes gold-plated copper alloy contacts with a half-beam termination type for reliable solder pin connections. It accommodates PCB thicknesses ranging from 1.37 mm to 1.78 mm (0.054 to 0.070 inches). Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.
