305-082-556-258

Edgeboard Connectors Overview

The EDAC Inc. 305-082-556-258 is a standard card edge connector header featuring 82 positions with a dual readout configuration. It utilizes a 3.96 mm (0.156 inch) contact pitch and a 3.56 mm row spacing. The component accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Designed for panel mounting, it employs a straddle mount style with vertical orientation. The contacts are gold-plated copper alloy, rated for 5 A current, while the thermoplastic insulator body supports an operating temperature range from -40°C to +105°C.
