305-056-520-201

Edgeboard Connectors Overview

The EDAC Inc. 305-056-520-201 is a standard card edge connector receptacle featuring 56 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for a board thickness of 1.57 mm (0.062 inch). The contacts are gold-plated copper alloy, ensuring reliable signal transmission with a current rating of 5 A. The housing is constructed from green thermoplastic polyester, providing durability across an operating temperature range of -40°C to +105°C. This component supports vertical PCB mounting with solder termination.
