305-020-500-508

Edgeboard Connectors Overview

The EDAC Inc. 305-020-500-508 is a standard card edge connector featuring 20 positions arranged in a dual row configuration. It utilizes a contact spacing of 3.96 mm (0.156 inches) and accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The component employs gold-plated copper alloy contacts to ensure reliable electrical performance. Designed for panel mounting, this vertical header offers a current rating of 5 A and operates within a temperature range of -40°C to +105°C. The insulator body is constructed from thermoplastic material, providing structural integrity and an insulation resistance of 5 GOhms.
