305-012-556-278

Edgeboard Connectors Overview

The EDAC Inc. 305-012-556-278 is a standard card edge connector from the 305 Series, designed for dual-edge board applications. It features 12 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum PCB thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts and solder pin termination for secure electrical connections. Rated at 5 A current capacity, it operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, ensuring reliable insulation and mechanical stability in panel-mounted vertical configurations.
