The DM1 Series SD Memory Card Connectors are designed for robust and reliable data storage applications. These connectors offer superior durability, withstanding significant insertion forces up to 400N and preventing damage to the SD card during accidental pull-outs with a release force of approximately 4N. A built-in lock feature ensures the card remains securely in place, while the push-in/push-out ejection mechanism simplifies card insertion and withdrawal. Designed to accommodate Secure Digital I/O cards, including those with Bluetooth communication modules, the DM1 Series is suitable for various expansion module integrations.
