SD Memory Card Connectors
DM1 Series
■Features
1. Withstands higher force of card insertion
Metal cover extends over the back of the connector
allowing it to withstand force of up to 400N (static load)
when dropped or accidentally hit. (Fig.1)
2. No damage to the card when accidentally
pulled-out
The connectors will release the card when a moderate
pull-out force of about 4N is applied. There will be no
damage to the lock components and all connector
functions will not be affected. (Fig.2)
3. Accidental card fall-out prevention
Built-in lock feature holds the card securely in place.
(Fig.3)
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.
