Product Overview

The DM3 Series microSD Card Connectors are designed for extremely small size and high reliability, making them the smallest on the market with above-the-board height. These connectors feature reverse card insertion protection, an effective ground and shield configuration for EMI protection, and a rigid and strong construction. Available in various models (DM3AT, DM3BT, DM3CS, DM3D), they offer different insertion and ejection mechanisms including Push-Push with ejection, Hinge Push-Pull, and Push-Pull manual operation. All models are suitable for applications requiring compact and robust microSD card connectivity.
