305-078-556-501

Edgeboard Connectors Overview

The EDAC Inc. 305-078-556-501 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 78 positions in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector accepts non-specified dual-edge cards and utilizes gold-plated copper alloy contacts with a solder pin termination type. It supports a continuous current rating of 5 A and offers insulation resistance of 5 GOhms. The housing is made of green thermoplastic material, suitable for operating temperatures ranging from -40°C to +105°C.
