Introduction
Product Overview
The HIROSE DM3 Series microSD Card Connectors are designed for extremely small size, offering market-leading compact dimensions and low above-board height. These connectors feature reverse card insertion protection, an effective ground and shield configuration for EMI protection, and a rigid, strong construction. Available in various models with different insertion/ejection mechanisms including Push-Push (with ejection) and Push-Pull (manual), they provide reliable card contact and easy termination inspection. Ideal for space-constrained applications requiring robust and secure microSD card connectivity.
