Product Description

Product Overview

The Hirose Electric DM3 Series microSD Card Connectors are designed for extremely small size and high reliability in compact electronic devices. These connectors offer reverse card insertion protection, effective ground and shield configuration for EMI protection, and a rigid, strong construction despite their small dimensions. Available in Push-Push (with ejection mechanism) and Push-Pull (manual insertion/ejection) variants, they ensure secure card retention and easy handling. Ideal for applications requiring space-saving and robust connectivity for microSD cards.
