SD Memory Card Connectors

Transcription

1 SD Memory Card Connectors DM Series Withstands higher force of card insertion. Card Standard type Metal cover extends over the back of the connector. Features. Withstands higher force of card insertion Metal cover extends over the back of the connector allowing it to withstand force of up to 4 N (static load) when dropped or accidentally hit.. No damage to the card when accidentally pulled-out The connectors will release the card when a moderate pull-out force of about 4 N is applied. There will be no damage to the lock components and all connector functions will not be affected. 3. Accidental card fall-out prevention Built-in lock feature holds the card securely in place. 4. Reliable Card Insertion and Withdrawal Built-in Push-in / Push-out ejection mechanism assures simple and reliable card insertion and withdrawal. 5. Designed to accept Secure Digital I/O card (Built-in Ground Contact) The connector allows use of various expansion modules, including the Bluetooth communication modules. Applications Notebook PC's, digital cameras, PDA's, audio/video equipment and other devices utilizing SD I/O cards. Card Reverse type Metal cover extends over the back of the connector. No damage to the card when accidentally pulled-out. Accidental card fall-out prevention C39
