305-022-556-501

Edgeboard Connectors Overview

The EDAC Inc. 305-022-556-501 is a standard card edge connector from the 305 series, designed for dual-edge female connections. It features 22 positions with a 3.96 mm (0.156 inch) pitch and supports board thicknesses between 1.37 mm and 1.78 mm. The connector utilizes gold-plated copper alloy contacts and solder pin termination. Rated for 5 A current and 1800 VACrms voltage, it operates within a temperature range of -40°C to +105°C. The housing is green thermoplastic, and it employs a vertical panel mount style.
