305-070-556-268

Edgeboard Connectors Overview

The EDAC Inc. 305-070-556-268 is a standard card edge connector from the 305 series, designed for dual-row applications with 70 positions. It features a 3.96 mm (0.156 inch) pitch and supports board thicknesses of 1.57 mm. The connector utilizes gold-plated copper alloy contacts with a solder pin termination type. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C. The housing is made of thermoplastic material, providing insulation resistance of 5 GOhms. This vertical panel-mount header ensures reliable electrical connections for dual-edge card interfaces.
