Durable MicroSD Card Connector Featuring EMI Shielding and Card Detection Switch HRS DM3AT-SF-PEJM5
Product Overview
The DM3 Series microSD Card Connectors from HIROSE ELECTRIC are designed for extremely small form factors and above-the-board height, offering the smallest dimensions on the market. These connectors feature reverse card insertion protection, an effective ground and shield configuration with 4-connection points for EMI protection, and a rigid, strong construction despite their compact size. They are available in various models with different insertion/ejection mechanisms, including Push-Push with ejection, Hinge Push-Pull, and Push-Pull manual operation, catering to diverse application needs. The series also includes a card detection switch and exposed termination leads for easy inspection and rework.
