305-058-521-202

Edgeboard Connectors Overview

The EDAC Inc. 305-058-521-202 is a standard card edge connector designed for dual-edge board insertion. It features 58 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum PCB thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and corrosion resistance. Rated for 5 A continuous current and 1800 VACrms insulation, it employs a solder pin termination style for secure panel mounting. The housing is constructed from green thermoplastic material, providing durability and environmental protection for vertical installation applications.
