391-038-520-201

Edgeboard Connectors Overview

The EDAC Inc. 391-038-520-201 is a dual female card edge connector from the 391 series, designed for high-reliability applications. It features 38 positions with a 0.100-inch (2.54mm) contact spacing and a 0.140-inch (3.56mm) row pitch. The connector utilizes gold-plated copper alloy contacts with a 10.0µin thickness to ensure stable electrical performance. Constructed with a black polyester thermoplastic insulator, it supports a wide operating temperature range of -40°C to +105°C. Designed for through-hole termination, this component provides robust mechanical stability for board-to-board or backplane connections.
