305-050-521-201

Edgeboard Connectors Overview

The EDAC Inc. 305-050-521-201 is a standard card edge connector from the 305 series, designed for dual-row female connections. It features 50 positions with a 3.96 mm (0.156 inch) pitch and accepts board thicknesses between 1.37 mm and 1.78 mm. The contacts are gold-plated copper alloy, providing a 5 A current rating and 1800 VACrms insulation capability. Constructed with thermoplastic polyester housing, it supports solder termination and operates within a temperature range of -40°C to +105°C.
