305-048-556-202

Edgeboard Connectors Overview

The EDAC 305-048-556-202 is a standard card edge connector featuring 48 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing. Designed for vertical panel mounting, the unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. Rated for 5 A current, the connector operates within a temperature range of -40°C to +105°C. The insulator body is made of thermoplastic material, providing structural integrity and electrical insulation.
