305-054-556-503

Edgeboard Connectors Overview

The EDAC 305-054-556-503 is a standard card edge connector featuring 54 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) pitch and accepts non-specified dual-edge cards with thicknesses between 1.37 mm and 1.78 mm. The unit employs gold-plated copper alloy contacts for reliable signal transmission and offers a 5 A continuous current rating. Designed for panel mount installation, it operates within a temperature range of -40°C to +105°C and includes insulation resistance of 5 GOhms.
