305-044-555-258

Edgeboard Connectors Overview

The EDAC Inc. 305-044-555-258 is a standard card edge connector from the 305 series, designed for dual female contact configurations with 44 positions. It features a 3.96 mm (0.156 inch) pitch and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component utilizes gold-plated copper alloy contacts and employs a solder pin termination method for secure attachment. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C. The insulator body is constructed from thermoplastic material, ensuring reliable performance in vertical panel mounting applications.
