305-020-500-208

Edgeboard Connectors Overview

The EDAC Inc. 305-020-500-208 is a standard card edge connector from the 305 series, designed for reliable signal transmission in electronic assemblies. It features a dual-row configuration with 20 positions and a pitch of 3.96 mm (0.156 inches). The component supports a PCB thickness of 1.57 mm and utilizes gold-plated copper alloy contacts to ensure low resistance and corrosion resistance. Rated for 5 A continuous current, it employs panel mount installation with solder eyelet termination. The thermoplastic polyester housing provides structural integrity across an operating temperature range of -40°C to +105°C.
