305-012-521-507

Edgeboard Connectors Overview

The EDAC Inc. 305-012-521-507 is a standard card edge connector from the 305 series, designed for vertical panel mounting applications. It features a dual female configuration with 12 positions and a 0.156-inch (3.96 mm) pitch. The connector utilizes gold-plated copper alloy contacts with a solder pin termination type. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, supporting board thicknesses between 1.37 mm and 1.78 mm.
