305-012-556-578

Edgeboard Connectors Overview

The EDAC Inc. 305-012-556-578 is a standard card edge connector designed for dual-edge board interfaces. It features 12 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and solder pin termination for secure electrical connections. Designed for panel mounting at a vertical angle, it accommodates PCBs with a thickness of 1.57 mm. The housing is constructed from green thermoplastic material, providing insulation resistance of 5 GOhms. It supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C.
